In the present work, four types of heterocyclic core-based polybenzoxazine matrices (HC-PBZ) developed based on pyridine, thiophene, and thiazole and their molecular structure, thermal, flame-retardant and luminescent properties were studied and discussed. The heterocyclic core-based benzoxazine monomers (HC-BZ) were synthesized using two types of phenols (phenol, and 4-hydroxyphenylacetonitrile), and two types of heterocyclic diamines [2,6-Bis-(4-aminophenyl)-4-thiophen-2-yl-pyridine (BATP) and 4-(2-methylthiazol-5-yl)-2,6-bis-(4-aminophenyl)-pyridine (BAMTP)] with formaldehyde through Mannich reaction. The structure of the four HC-BZ monomers was confirmed by various spectral analysis such as Fourier-transform infrared spectroscopy (FTIR), and Nuclear magnetic resonance spectroscopy ((HNMR)-H-1 and (CNMR)-C-13). All the four HC-BZ monomers have the maximum range of curing temperature (T-p) between 252 and 267 degrees C. Data resulted from the thermal studies indicate that the HC-PBZ exhibits better T-g,T- thermal stability and flame-retardant properties. Among the four HC-PBZ systems the thiazole based system possesses the higher value of T-g of 268 degrees C and thermal stability when compared to those of other matrices. It was also observed that the HC-BZ monomers and HC-PBZ polymers exhibit a photoluminescent (PL) emission range between 441-445 and 414-417nm, respectively. Overall, it seems that the thiazole and thiophene based HC-PBZ can be considered as competitive materials for luminescent applications with high thermal and flame-retardant properties.

The West Nile Virus (WNV) NS2B-NS3 protease is an attractive target for the development of therapeutics against this arboviral pathogen. In the present investigation, the screening of a small library of fifty-eight synthetic compounds against the NS2-NB3 protease of WNV is described. The following groups of compounds were evaluated: 3-(2-aryl-2-oxoethyl)isobenzofuran-1(3H)-ones; eugenol derivatives bearing 1,2,3-triazolic functionalities; and indan-1,3-diones with 1,2,3-triazolic functionalities. The most promising of these was a eugenol derivative, namely 4-(3-(4-allyl-2-methoxyphenoxy)-propyl)-1-(2-bromobenzyl)-1H-1,2,3-triazole (35), which inhibited the protease with IC50 of 6.86 mu mol L-1. Enzyme kinetic assays showed that this derivative of eugenol presents competitive inhibition behaviour. Molecular docking calculations predicted a recognition pattern involving the residues His(51) and Ser(135), which are members of the catalytic triad of the WNV NS2B-NS3 protease.

Application In Synthesis of 1-(4-Nitrophenyl)ethanone. Shtukenberg, AG; Zhu, XL; Yang, YF; Kahr, B in [Shtukenberg, Alexander G.; Zhu, Xiaolong; Yang, Yongfan; Kahr, Bart] NYU, Dept Chem, New York, NY 10003 USA; [Shtukenberg, Alexander G.; Zhu, Xiaolong; Yang, Yongfan; Kahr, Bart] NYU, Mol Design Inst, New York, NY 10003 USA published Common Occurrence of Twisted Molecular Crystal Morphologies from the Melt in 2020, Cited 49.

Two books that describe the forms of thin films of many molecular crystals grown from the melt in polarized light, Gedrillte Kristalle (1929) by Ferdinand Bernauer and Thermomicroscopy in the Analysis of Pharmaceuticals (1971) by Maria Kuhnert-Brandstatter, are analyzed. Their descriptions, especially of curious morphologies consistent with helicoidal twisting of crystalline fibrils or narrow lamellae, are compared in the aggregate with observations from our laboratory collected during the past 10 years. According to Bernauer, 27% of molecular crystals from the melt adopt helicoidal crystal forms under some growth conditions even though helicoids are not compatible with long-range translational symmetry, a feature that is commonly thought to be an a priori condition for crystallinity. Bernauer’s figure of 27% is often met with surprise if not outright skepticism. Kuhnert-Brandstatter was aware of the tell-tale polarimetric signature of twisting (rhythmic interference colors) but observed this characteristic morphology in less than 0.5% of the crystals described. Here, the experience of the authors with 101 arbitrarily selected compounds-many of which are polymorphous-representing 155 total crystal structures, shows an even higher percentage (ca. 31%) of twisted crystals than the value reported by Bernauer. These observations, both positive (twisting) and negative (no twisting), are tabulated. It is concluded that twisting is not associated with molecular structure or crystal structure/symmetry. Rather, these nonclassical morphologies are associated with certain habits with exaggerated aspect ratios, and their appearance is strongly controlled by the growth conditions. Comments are offered in an attempt to reconcile the observations here, and those of Bernauer, the work of seekers of twisted crystals, with those of Kuhnert-Brandstatter, whose foremost consideration was the characterization of polymorphs of compounds of medicinal interest.

The highly diastereoselective synthesis of perfluoroalkyl-containing pyrano[3,4-c]pyrroles has been accomplished via a cascade process involving Michael addition, Passerini-type reaction, Mumm rearrangement and an oxo-Diels-Alder reaction. This domino transformation of isocyanides, methyl perfluoroalk-2-ynoates and 3-aroyl (or heteroyl) acrylic acids proceeded smoothly at room temperature and led to the formation of the highly diastereoselective target compounds with high functional-group compatibility in good to excellent yields.

A strategy for heterogeneous copper(I) mesoporous silica [Cu(I)-SBA-15] mediated catalytic reduction has been developed for the reduction of various nitroarenes in excellent yields. In addition to alcothermal strategy, other strategies have been attempted for the preparation of Cu(I) substituted mesoporous silica, however, the desired oxidation state is obtained only through alcothermal strategy. The crystalline phases and oxidation state of synthesized materials were characterized by XRD and XPS measurements and tested for catalytic reduction of nitroarenes. Among the tested materials, the best catalytic reduction of nitroarenes with an excellent substrate scope and good catalytic reusability was established by Cu(I)-SBA-15 material. The reduction kinetics and the controlled experimental studies reveal that the reaction proceeds through pseudo-first-order kinetics and nitrosobenzene intermediate pathway.

We report the one-pot synthesis of 2,2-disubstituted chromanes with electron-withdrawing substituents. This reaction provides a simple yet efficient route to a wide range of electron-deficient chromanes in high yield and excellent regioselectivity. The reaction of salicylaldehyde with 1,1-disubstituted ethylenes smoothly furnishes these electron-deficient chromanes, which can be further transformed into functionalized chromanes or chromene. For example, BW683C was effectively synthesized from 5-chlorosalicylaldehyde with 4-chlorostyrene in two steps in excellent yield. The present reaction thus provides versatile access to functionalized electron-deficient chromanes and chromenes and therefore constitutes a promising tool for the synthesis of biologically and photochemically active molecules.

We have examined enantioselective bioreduction of acetophenone and its substituted derivatives into corresponding S-alcohols catalyzed by Daucus carota and Petroselinum crispum plant cells in water and isooctane. We found that the nature of the substituent has a profound effect on the relative reactivity of substituted acetophenones and enantioselectivity of biocatalytic reduction. Electron-withdrawing substituents -Br and -NO2 enhance the initial rate of reaction and yields of products, while electron donating substituent -OCH3 decreases them. The reduction rates and yields of products in water were noticeably higher in comparison with similar reductions conducted in isooctane. Correlations between the initial reaction rate and the substituent constant (sigma(+)) in the aromatic ring characterizing its nature were established. Comparison of rho constants of bioreduction catalyzed by D. carota and P. crispum shows that the sensitivity of the reduction to the nature of the substituents is more significant in the case of D. carota biocatalyst. Comparison of rho constants for D. carota and P. crispum in water and isooctane indicates that the sensitivity of bioreduction to the nature of the substituent tends to increase from water to isooctane.

We demonstrate a method to boost the photocatalysis of titania by constructing a core-shell structure. The crucial technique is to capsulate the titania nanoparticles by a sheath of nitrogen-doped carbon (TiO2@N-AC) with a thickness at 3.5-7.5 nm, which creates an exceptional effect to accelerate the catalytic hydrogenation of substituted nitroarenes with isopropanol as the hydrogen source under ultraviolet or visible-light irradiation. In the catalytic hydrogenation of various nitroarenes with substituted groups of -Cl, -F, -C-C, -C-O, and -C=N, TiO2@N-AC exhibits high conversions and selectivities to the corresponding functionalized anilines, even outperforming the catalysts containing noble metals. Mechanism study demonstrates that the TiO2@N-AC catalyst benefits the selective adsorption of the nitro group rather than other substituted groups, which efficiently avoids the undesirable side reactions. Importantly, the catalyst is stable and exhibits constant performances in the continuous recycling tests.

The hydrogenation of nitrobenzene to aniline is an important process in the industry of fine chemicals, but developing inexpensive catalysts with expected activity and selectivity still remains a challenge. By using density functional theory calculations, we demonstrated that the isolated Fe atom not only can weaken the adsorption of reactants and reaction intermediates as compared to Fe nanoparticles, but also remarkably decrease the reaction barrier for the hydrogenation of nitrobenzene to aniline. Thus, the Fe single-atom (Fe SA) catalyst is considered as an ideal catalyst for this reaction. This theoretical prediction has been subsequently confirmed by experimental results obtained for the Fe SAs loaded on N-doped hollow carbon spheres (Fe SAs/NHCSs) which achieved a conversion of 99% with a selectivity of 99% for the hydrogenation of nitrobenzene. The results significantly outperformed the Fe nanoparticles for this reaction. This work provides theoretical insight for the rational design of new catalytic systems with excellent catalytic properties.
