A convenient and efficient method for the regioselective macrocyclization of triazole bridged spiropyrrolidine-oxindole, and bis-spiropyrrolizidine-oxindole derivatives was accomplished through intra and self-intermolecular [3 + 2] cycloaddition of azomethine ylides. The chalcone isatin precursors 9a-i required for the click reaction were obtained from the reaction of N-alkylazidoisatin 4 and propargyloxy chalcone 8a-i which in turn were obtained by the aldol condensation of propargyloxy salicylaldehyde 6 and substituted methyl ketones 7a-i. The regio- and stereochemical outcome of the cycloadducts were assigned based on 2D NMR and confirmed by single crystal XRD analysis. High efficiency, mild reaction conditions, high regio- and stereoselectivity, atom economy and operational simplicity are the exemplary advantages of the employed macrocyclization procedure.

An efficient continuous flow process for the synthesis of 5-substituted 1H-tetrazoles is described. The process involves the reaction between a polymer-supported triorganotin azide and organic nitriles. The polymer-supported organotin azide, which is in situ generated with a polystyrene-supported triorganotin alkoxide and trimethylsilylazide, is immobilized in a packed bed reactor. This approach is simple, fast (it takes from 7.5 to 15 min), and guarantees a low concentration of tin residues in the products (<5 ppm). The process was developed to aryl-, heteroaryl-, and also alkylnitriles and was applied for the synthesis of valsartan, an angiotensin II receptor antagonist.

A green chemical preparation of Pd nanoparticles (NPs) embedded in phytochemical resins using a plant extract from Pulicaria odora L. and PdCl2 under ambiant conditions is reported. Two batches of Pd NPs have been prepared: they present homogeneous sizes of respectively 2.2 nm and 3.2 nm depending on the preparation conditions. The Pd NPs were characterized by different techniques (TEM, HRTEM, XRD, XPS and BET) and have been successfully used for the reduction of nitroarenes in EtOH under H-2 at atmospheric pressure at rt in the presence of only 5 mequiv. of Pd. Finally the Pd NPs embedded in resin particles were easily recovered by filtration and used at least seven times without significant loss in efficiency. The residual amount of palladium found in the reaction product is very low (<0.6% of the initial amount). Therefore both preparation of the Pd NPs and their use for hydrogenations of nitroarenes are environmentally benign.

A three-component transition-metal-free aerobic method for the generation of 1,4-benzothiazines is reported herein. The KI/DMSO/O-2 system was found to be effective for the oxidative cyclization/coupling of 2-aminobenzenethiols, anilines, and methylketones. Hence, various structurally important imino 1,4-benzothiazines were assembled with broad functional group tolerance. Mechanistic studies revealed an initial oxidation of ketone alpha C-H bonds by the KI/DMSO/O-2 oxidative system.

Cost-effective and efficient photocatalysis are highly desirable in chemical synthesis. Here we demonstrate that readily prepared suspensions of APbBr(3) (A = Cs or methylammonium (MA)) type perovskite colloids (ca. 2-100 nm) can selectively photocatalyze carbon-carbon bond formation reactions, i.e., alpha-alkylations. Specifically, we demonstrate alpha-alkylation of aldehydes with a turnover number (TON) of over 52,000 under visible light illumination. Hybrid organic/inorganic perovskites are revolutionizing photovoltaic research and are now impacting other research fields, but their exploration in organic synthesis is rare. Our low-cost, easy-to-process, highly efficient and bandedge-tunable perovskite photocatalyst is expected to bring new insights in chemical synthesis.

Herein, we describe the formation of quaternary carbon centers with excellent diastereoselectivity via a strain-release protocol. An organometallic species is generated by Cp*Rh(III)-catalyzed C-H activation, which is then coupled with strained bicyclobutanes (BCBs) and a prochiral carbon electrophile in a three-component reaction. This work illustrates a rare example of BCBs in transition metal catalysis and demonstrates their broad potential to access novel reaction pathways. The method developed exhibits ample functional group tolerance, and the products can be further transformed into valuable alpha-quaternary beta-lactones. Preliminary mechanistic investigations suggest a twofold C-C bond cleavage sequence involving sigma-bond insertion and an ensuing beta-carbon elimination event.

On the pharmaceutical account of the reported anticancer activity of benzothiazole derivatives, differently substituted benzothiazole derivatives 2a-c to 34a,b, attached at 2-position to different heterocyclic moieties, were synthesized via different chemical reactions. Thirteen of the newly synthesized compounds were selected by the National Cancer Institute, Bethesda, Maryland, USA, and evaluated for their in vitro antitumor activity against 60 human tumor cell lines in a one-dose screening panel among which two compounds 4 and 17 showed high activity and were selected for further evaluation in the five-dose full panel assay, in which compound 4 exerted powerful growth inhibitory activity against all cell lines with GI(50) ranging from 0.683 to 4.66 mu M/L in addition to excellent lethal activity against most of the cell lines.

A non-noble heterogeneous catalyst, ultra dispersed Co anchored on ordered porous nitrogen-riched carbon (CoN@PCN) was fabricated through a sacrificial-template pyrolysis strategy, in which SBA-15 and 1, 10-phenanthroline were employed as the hard template and ligand, respectively. Co was ultra dispersed owing to the confinement effect of SBA-15 and the strong coordination effect of Co with phenanthroline. The CoN@PCN displayed excellent catalytic activity and selectivity for the hydrogenation of nitroarenes with ammonia-borane as hydrogen donor under mild conditions, which can be ascribed to the ultra dispersed Co sites, high adsorption ability of the catalyst for ammonia-borane, large specific surface area and abundant porous structure of CoN@PCN. Based on the results of density functional theory calculations, the catalytic mechanism of CoN@PCN for the hydrogenation reaction was proposed. The recycled CoN@PCN had no obvious change in catalytic performance after five consecutive cycles, indicating its durability and recyclability.

We report an efficient HCl center dot DMPU assisted one-pot conversion of aldehydes into nitriles. The use of HCl center dot DMPU as both an acidic source as well as a non-nucleophilic base constitutes an environmentally mild alternative for the preparation of nitriles. Our protocol proceeds smoothly without the use of toxic reagents and metal catalysts. Diverse functionalized aromatic, aliphatic and allylic aldehydes incorporating various functional groups were successfully converted to nitriles in excellent to quantitative yields. This protocol is characterized by a broad substrate scope, mild reaction conditions, and high scalability.
