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. Recommanded Product: 86-29-3.

Taking advantage of computational chemistry, the best diamine for the synthesis of a multi-dentate ligand from the reaction with 3-(trimethoxysilyl) propylisocyanate (TEPI) was selected. Actually, predictive Density Functional Theory (DFT) calculations provided the right diamino chain, i.e. ethylenediamine, capable to sequester a palladium atom, together with the relatively polar solvent toluene, and then undergo the experiments as a selective catalytic agent. The ligand was then prepared and applied for the decoration of the halloysite (Hal) outer surface to furnish an efficient support for the immobilization of Pd nanoparticles. The resulting catalyst exhibited high catalytic activity for hydrogenation of nitroarenes. Moreover, it showed high selectivity towards nitro functional group. The study of the catalyst recyclability confirmed that the catalyst could be recycled for several reaction runs with only slight loss of the catalytic activity and Pd leaching. Hot filtration test also proved the heterogeneous nature of the catalysis.

Twelve new chiral chelating resins have been prepared using solid phase organic synthesis with the Merrifield and Wang resins and the bidentate amine 1,2-ethylenediamine, followed by the coupling of asymmetric ketones such as 1-phenyletanone, 4-methyl-2-pentanone 4-nitroacetophenone and 4-methoxyacetophenone to form prochiral imines. The enantioselective reduction with borane and (R)-(+)-2-Methyl-CBS-oxazaborolidine leads to the chiral resins with yields greater than 86%. We used these chiral resins to prepare 24 reducing complexes with alkali tetrahydroborates in a very simple way giving yields greater than 87%. Finally, we achieved a preliminary enantioselective reduction of acetophenone employing the Merrifield’s chiral chelating resins obtaining the corresponding S alcohol in a 70:30 ratio with the R analog alcohol.

A series of donor-acceptor pyranones (3a-m, 4a-h) were synthesized using alpha-oxo-ketene-S,S-acetal as the synthon for their application as emissive materials for energy-saving organic light-emitting devices (OLEDs). Among them, five pyranones 3f, 3g, 3h, 3m, and 4e exhibited highly bright fluorescence in the solid state and weak or no emission in the solution state. Photophysical analysis of these dyes revealed that only 3f and 3m showed aggregation-induced emission behavior in a THF/water mixture (0-99%) with varying water fractions (f(w)) leading to bright fluorescence covering the entire visible region, while other derivatives 3g, 3h, and 4e did not show any fluorescence signal. The computational studies of the compounds revealed that the longer wavelength absorption originates from HOMO to LUMO electronic excitation. These dyes exhibited good thermal stability with 5% weight loss temperature in the range of 218-347 degrees C. The potential application of the donor-acceptor pyranone dyads was demonstrated by fabrication of solution-processed OLEDs. Remarkably, OLED devices prepared using highly emissive compounds 6-(anthracen-9-yl)-4-(methylthio)-2-oxo-2H-pyran-3-carbonitrile (3m) and 6-(4-methoxyphenyl)-4-(methylthio)-2-oxo-2H-pyran-3-carbonitrile (3f) displayed pure white emission with CIE coordinates of (0.29, 0.31) and (0.32, 0.32), respectively. Additionally, the resultant devices exhibited external quantum efficiencies of 1.9 and 1.2% at 100 cd m(-2), respectively.

It is a persistent target to develop noble-metal-free catalysts that can achieve chemoselective hydrogenation of nitro compounds under mild reaction conditions. In this work, we report a new strategy for preparation of hydrogenation catalysts containing both CoNx and CoyZnS supported on N-doped porous carbon (CoNx-CoyZnS@NPC-Z). The CoNx-CoyZnS@NPC-Z catalysts were prepared by pyrolyzing the protein-metal-ion networks, followed by treatment with acid. We found that CoNxCoyZnS@NPC-3 catalyst delivers high catalytic activity and selectivity, affording almost full conversion and >98% selectivity in water/methanol mixture solvents at 90 degrees C under 5 bar of H-2 pressure for 3 h of reaction. Notably, the catalytic hydrogenation can work even under 1 bar of H-2 pressure and at room temperature with high conversion and selectivity. Besides, CoNx-CoyZnS@NPC-3 exhibits remarkable tolerance to CO or H2S poisoning and acid erosion.

A new methodology for the carbonylative transformation of N-fluoro-sulfonamides into N-sulfonyl-beta-homoproline esters has been described. In the presence of a catalytic amount of Cu(OTf)(2), a range of beta-homoproline derivatives were prepared in moderate to good yield. The reaction proceeds via the intramolecular cyclization and intermolecular carbonylation of a free carbon radical. Notably, this procedure offers the possibility to build potential functionalized bioactive molecules.

The kinetics of intramolecular-contact formation between remote functional groups in peptides with restricted conformational flexibility were examined using designed peptides with variable-length proline bridges. As probes for this motion, free radicals were produced using the center dot OH-induced oxidation at the C-terminal methionine residue of gamma-Glu-(Pro)(n)-Met peptides (n = 0-3). The progress of the radicals’ motion along the proline bridges was monitored as the radicals underwent reactions along the peptides’ backbones. Of particular interest was the reaction between the sulfur atom located in the side chain of the oxidized Met residue and the unprotonated amino group of the glutamic acid moiety. Interactions between them were probed by the radiation-chemical yields (expressed as G values) of the formation of C-centered, alpha-aminoalkyl radicals (alpha N) on the Glu residue. These radicals were monitored directly or via their reaction with p-nitroacetophenone (PNAP) to generate the optically detected PNAP(center dot-) radical anions. The yields of these alpha N radicals were found to be linearly dependent on the number of Pro residues. A constant decrease by 0.09 mu M J(-1) per spacing Pro residue of the radiation-chemical yields of G(alpha N) was observed. Previous reports support the conclusion that the alpha N radicals in these cases would have to result from (S.*.N)(+)-bonded cyclic radical cations that arose as a result from direct contact between the ends of the peptides. Furthermore, by analogy with the rate constants for the formation of intramolecularly (S.*.S)(+)-bonded radical cations in Met-(Pro)-Met peptides (J. Phys. Chem. B 2016, 120, 9732), the rate constants for the formation of intramolecularly (S.*.N)(+)-bonded radical cations are activated to the same extent for all of the gamma-Glu-(Pro)(n)-Met peptides. Thus, the continuous decrease of G(alpha N) with the number of Pro residues (from 0 to 3) suggests that the formation of a contact between the S-atom in the C-terminal Met residue and the N-atom of a deprotonated N-terminal amino group of Glu is controlled in peptides with 0 to 3 Pro residues by the relative diffusion of the S center dot+ and unoxidized N-atom. The overall rate constants of cyclization to form the (S.*.N)-bonded radical cations were estimated to be 3.8 X 10(6) , 1.8 x 10(6) , and 8.1 x 10(5) s(-1) for peptides with n = 0, 1, and 2 Pro residues, respectively. If activation is the same for all of the peptides, then these rate constants are a direct indication for the end-to-end dynamics along the chain.

A three-component reaction has been developed for the construction of multiaryl-substituted pyrrole derivatives from arylketones, amines, and nitrovinylarenes under metal- free conditions. Hence, homologous 1,2,4-triaryl-substituted pyrrole products were obtained in good to high yields. Furthermore, 2,3,5-triaryl-substituted pyrroles were selectively formed in the absence of nitrovinylarenes. The photophysical properties of some pyrrole products have been investigated to show good aggregation-induced emission (AIE) activity.

C-Glycosides are both a common motif in many bioactive natural products and important glycoside mimetics. We demonstrate that activating a hemiacetal with a sulfonyl chloride, followed by treating the resultant glycosyl sulfonate with an enolate results in the stereospecific construction of beta-linked C-glycosides. This reaction tolerates a range of acceptors and donors, including disaccharides. The resulting products can be readily derivatized into C-glycoside analogues of beta-glycoconjugates, including C-disaccharide mimetics.
