Alcohol dehydrogenases (ADHs) together with the economical substrate-coupled cofactor regeneration system play a pivotal role in the asymmetric synthesis of chiral alcohols; however, severe challenges concerning the poor tolerance of enzymes to 2-propanol and the adverse effects of the by-product, acetone, limit its applications, causing this strategy to lapse. Herein, a novel ADH gene smadh2 was identified from Stenotrophomonas maltophilia by traditional genome mining technology. The gene was cloned into Escherichia coli cells and then expressed to yield SmADH2. SmADH2 has a broad substrate spectrum and exhibits excellent tolerance and superb activity to 2-propanol even at 10.5 M (80%, v/v) concentration. Moreover, a new thermostatic bubble column reactor (TBCR) system is successfully designed to alleviate the inhibition of the by-product acetone by gas flow and continuously supplement 2-propanol. The organic waste can be simultaneously recovered for the purpose of green synthesis. In the sustainable system, structurally diverse chiral alcohols are synthesised at a high substrate loading (>150 g L-1) without adding external coenzymes. Among these, about 780 g L-1 (6 M) ethyl acetoacetate is completely converted into ethyl (R)-3-hydroxybutyrate in only 2.5 h with 99.9% ee and 7488 g L-1 d(-1) space-time yield. Molecular dynamics simulation results shed light on the high catalytic activity toward the substrate. Therefore, the high 2-propanol tolerance SmADH2 with the TBCR system proves to be a potent biocatalytic strategy for the synthesis of chiral alcohols on an industrial scale.

Name: 2,2-Diphenylacetonitrile. I found the field of Chemistry very interesting. Saw the article Three-Component, Interrupted Radical Heck/Allylic Substitution Cascade Involving Unactivated Alkyl Bromides published in 2020, Reprint Addresses Glorius, F (corresponding author), Westfalische Wilhelms Univ Munster, Organ Chem Inst, D-48149 Munster, Germany..

Developing efficient and selective strategies to approach complex architectures containing (multi)stereogenic centers has been a long-standing synthetic challenge in both academia and industry. Catalytic cascade reactions represent a powerful means of rapidly leveraging molecular complexity from simple feedstocks. Unfortunately, carrying out cascade Heck-type reactions involving unactivated (tertiary) alkyl halides remains an unmet challenge owing to unavoidable beta-hydride elimination. Herein, we show that a modular, practical, and general palladium-catalyzed, radical three-component coupling can indeed overcome the aforementioned limitations through an interrupted Heck/allylic substitution sequence mediated by visible light. Selective 1,4-difunctionalization of unactivated 1,3-dienes, such as butadiene, has been achieved by employing different commercially available nitrogen-, oxygen-, sulfur-, or carbon-based nucleophiles and unactivated alkyl bromides (>130 examples, mostly >95:5 E/Z, >20:1 a). Sequential C(sp(3))-C(sp(3)) and C-X (N, O, S) bonds have been constructed efficiently with a broad scope and high functional group tolerance. The flexibility and versatility of the strategy have been illustrated in a gram-scale reaction and streamlined syntheses of complex ether, sulfone, and tertiary amine products, some of which would be difficult to access via currently established methods.

Chiral, cationic NHC-iridium complexes are introduced as catalysts for the intramolecular hydroamination reaction of unactivated aminoalkenes. The catalysts show high activity in the construction of a range of 5- and 6-membered N-heterocycles, which are accessed in excellent optical purity, with various functional groups being tolerated with this system. A major deactivation pathway is presented and eliminated by using alternative reaction conditions. A detailed experimental and computational study on the reaction mechanism is performed providing valuable insights into the mode of action of the catalytic system and pointing to future modifications to be made for this catalytic platform.

This work reports the use of homogeneous and silica immobilized palladium(II) complexes of ligands (2-phenyl-2-((3(triethoxysilyl)propyl)imino)ethanol) (L1), (4-methyl-2-((3(triethoxysilyl)propyl)imino)methyl)phenol) (L2), [L1-MCM-41] (L1im), and [L2-MCM-41] (L2im) as catalysts in molecular hydrogenation of alkenes, alkynes and functionalized benzenes. The homogeneous complexes [Pd(L1)(2)] (Pd1), [Pd(L2)(2)] (Pd2), [Pd(L1)(Cl-2)] (Pd3), and [Pd(L2)(Cl-2)] (Pd4), and their respective silica immobilized complexes [Pd(L1)(2)]-MCM-41] (Pd1im), [Pd(L2)(2))-MCM-4] (Pd2im), [Pd (L1)(Cl-2)-MCM-41] (Pd3im) and [Pd(L2)(Cl-2)]-MCM-41] (Pd4im) formed active catalysts in the molecular hydrogenation of these substrates. The catalytic activities and product distribution in these reactions were largely dictated by the nature of the substrate. The kinetic studies revealed a pseudo-first order dependence on styrene substrate for both the homogeneous and immobilized catalysts. Significantly, the selectivity of both homogeneous and immobilized catalysts were comparable in the hydrogenation of both alkynes and multi-functionalized benzenes. The supported catalysts could be recycled up to four times with minimum loss of catalytic activity and showed absence of any leaching from hot filtration experiments. Kinetics and poisoning studies established that complexes Pd1-Pd4 were largely homogeneous in nature, while the immobilized complexes Pd1im-Pd4im formed Pd(0) nanoparticles as the main active species.

A simple and efficient continuous flow methodology has been developed for hydrogenation and reductive deuteration of nitriles to yield primary amines and also valuable alpha,alpha-dideutero analogues. Raney nickel proved to be a useful catalyst for the transformation of a wide range of nitriles under reasonably mild conditions with excellent deuterium incorporation (>90 %) and quantitative conversion. Among known model compounds, three new deuterated primary amines were prepared. The large-scale synthesis of deuterated tryptamine was also carried out to deliver 1.1 g product under flow conditions.

The aim of the present study is to design and synthesis of new pyrazole-triazolopyrimidine hybrids as potent alpha-glucosidase inhibitors. The target compounds 4a-n were synthesized by one-pot multicomponent approach with good yields and were characterized by various spectroscopic techniques and finally by single crystal X-ray diffraction method (4j). All the newly-synthesized derivatives have been screened for their alpha-glucosidase enzyme inhibition activity and acarbose taken as a standard drug. Among all the tested compounds, 4h has displayed excellent alpha-glucosidase enzyme inhibition activity with IC50 value 12.45 mu M to the standard drug acarbose (IC50: 12.68 mu M). Similarly, the compounds 4f and 4l have exhibited potent activity with IC50 values 14.47 mu M and 17.27 mu M respectively. Structure-activity relationship (SAR) studies of all the title compounds were established. The mode of binding interactions between the alpha-glucosidase enzyme and the compounds were studied. The drug-likeness properties (Lipinski parameters and in silico ADME properties) have predicted for the target compounds. The alpha-glucosidase inhibition, molecular docking and drug-likeness properties of the compounds 4h, 4f and 4l were suggested that these are promising hits for anti-diabetic activity.

Porous organic polymers (POPS) containing nitrogenous substituents have potential practical applications as heterogeneous catalysts based upon controlled porous structure and surface-anchored noble metal nanoparticles (NMNPs). In this work we prepared a POP material from piperazine and cyanuric chloride starting materials (PC-POP). The PC-POP material contains numerous triazinyl moieties, thus rendering the pores hydrophobic. Subsequently, by means of a novel reverse double-solvent approach (RDSA), microdroplets of Pd(AcO)(2)/CH2Cl2 were introduced into the hydrophobic pores of PC-POP in an aqueous environment; Pd(II) was rapidly reduced by NaBH4 to form ultra-fine Pd NPs and confined within the pores of PC-POP at high dispersity. The extensive porosity and dispersity of the Pd NPs made the active sites readily accessible, and led to efficient mass transfer. Thus, Pd@PC-POP exhibits superior catalytic performance in catalytic reduction of various nitroarenes. Furthermore, Pd@PC-POP has excellent recyclability, without significant loss of activity nor leaching of Pd active sites during 10 successive reaction cycles. This work points to a practical and cost-effective approach to preparation of POP materials, and also for confining ultra-fine NMNPs in POPs for use as catalysts. (C) 2018 Elsevier Inc.

Structural and third-order nonlinear optical (NLO) properties of two D-pi-A-pi-A [(2E)-3-(3-chlorophenyl)-1-(3-nitrophenyl)prop-2-en-1-one (3C3NC) and (2E)-3-(4-fluorophenyl)-1-(4-nitrophe nyl)prop-2-en-1-one (FNC)] and one D-pi-A-pi-D [(2E)-1-(9-anthryl)-3-(4-fluorophenyl) prop-2-en-1-one (FANC)] type chalcone derivatives were investigated experimentally as well as theoretically. All the three chalcones are centrosymmetric (CS) and crystallized in P2(1)/c space group. In crystal packing, all compounds exhibit CeH center dot center dot center dot O hydrogen bonds and pi center dot center dot center dot pi interactions. From UV-Vis-NIR absorption spectra, the cut-off wavelength and optical band gaps of the chalcones were evaluated. The thermal stability and the melting point of the chalcones were determined from the TGA/DTA techniques. The ultrafast third-order NLO properties of the three chalcones in solution (0.01 M) were evaluated by Z-scan technique using femtosecond (fs) pulses from Ti: Sapphire laser (similar to 150 fs, 80 MHz, 800 nm). Third-order nonlinear absorption (NLA) coefficient (beta similar to 10(-9) cmW(-1)), nonlinear refraction (NLR) index (n(2)similar to 10(-14) cm(2)W(-1)), susceptibility (chi((3)) similar to 10(-12) esu) and molecular hyperpolarizability (gamma(h) similar to 10(-31) esu) were unambiguously determined. The chalcones satisfy the condition to observe reverse saturable absorption (RSA) mechanism (sigma(ex) > sigma(g)). Further, the larger values of sigma(ex)/sigma(g) (similar to 2-3) indicate that the chalcones would exhibit remarkable optical limiting property. The estimated optical limiting (OL) threshold values are in the order of mu J/cm(2). Further, all the chalcones have satisfied the one-photon and two-photon figures of merit conditions (W > 1 and T < 1) for the optical switching applications. In addition to experimental findings, the optimized geometry, HOMO-LUMO energy gap, NLO parameters such as electronic dipole moment, polarizability, first and second hyperpolarizabilities of all the three chalcones were determined theoretically (DFT) for different wavelength at B3LYP/6-311 thorn G (d,p) basic set. The experimentally determined second-order susceptibilities (Z-scan technique) are reasonably in agreement with the computational values (TD-DFT). The MEP surface revealed that the 3C3NC, FNC and FANC molecules have some potential sites for electrophilic and nucleophilic attack. The experimental and computational NLO data clearly suggest that the nonlinearity of chalcone molecules greatly depends on the electron donor and acceptor strengths of the substituents. Further, all the chalcones are potential materials for optical limiting and optical switching applications. (C) 2020 Elsevier B.V. All rights reserved.

Four new piperine derivatives, PC1-PC4, were synthesized, and their structures were fully characterized by infrared (IR) and H-1 and C-13 nuclear magnetic resonance (NMR) spectroscopies. Quantum chemical calculations were performed using density functional theory (DFT) with the B3LYP-D3/6-31G(d,p) and 6-311+G(2d,p) basis sets. Electronic properties, such as the energy gap between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) and some global chemical reactivity descriptors, were evaluated to study the reactivity and stability of the compounds. H-1 and C-13 NMR chemical shifts were calculated by using the gauge-invariant atomic orbital (GIAO) method and compared with experimental values. In addition, the compounds were evaluated in an antifungal study against Candida, Trichophyton and Microsporum strains, and only PC4 showed 70% inhibition in ten tested strains, with a minimum inhibitory concentration (MIC) ranging from 1.23-2.46 mu mol mL(-1) and a minimum fungicide concentration (MFC) ranging from 9.84-19.68 mu mol mL(-1), and presented a fungistatic effect.
