A copper-catalyzed intermolecular three-component asymmetric radical 1,2-carboalkynylation of alkenes has been developed, providing straightforward access to diverse chiral alkynes from readily available alkyl halides and terminal alkynes. The utilization of a cinchona alkaloid-derived multidentate N,N,P-ligand is crucial for the efficient radical generation from mildly oxidative precursors by copper and the effective inhibition of the undesired Glaser coupling side reaction. The substrate scope is broad, covering (hetero)aryl-, alkynyl-, and aminocarbonyl-substituted alkenes, (hetero)aryl and alkyl as well as silyl alkynes, and tertiary to primary alkyl radical precursors with excellent functional group compatibility. Facile transformations of the obtained chiral alkynes have also been demonstrated, highlighting the excellent complementarity of this protocol to direct 1,2-dicarbofunctionalization reactions with C(sp(2)/sp(3))-based reagents.

The -CHF2 moiety has shown a growing interest in pharmaceutical and agrochemical applications over the last few years. Its introduction is therefore a current research topic for organic chemists. Several groups have reported the synthesis of difluoromethylated compounds. However, the more challenging enantioselective introduction of the difluoromethyl group has been scarcely described yet. We recently developed a new strategy, based on the use of an enantiopure difluoromethyl sulfoxide used as chiral and traceless auxiliary, for the synthesis of highly enantioenriched alpha-difluoromethyl alcohols. The first method developed in our laboratory aims to access highly stereoenriched alpha,alpha-difluoro-beta-hydroxysulfoxides through the condensation of the enantiopure difluoromethyl sulfoxide on carbonyl derivatives. It is noteworthy that highly diastereo- and enantioenriched alpha,alpha-difluoro-beta-hydroxysulfoxides can also be accessed after the diastereoselective reduction of highly enantioenriched alpha,alpha-difluoro-beta-ketosulfoxides. Finally, the expected difluoromethyl-substituted alcohols can be obtained after removal of the chiral auxiliary with complete retention of stereoenrichment at carbon. (C) 2019 Elsevier Ltd.

The chalcone and bis-chalcone derivatives have been synthesized under sonication conditions via Claisen-Schmidt condensation with KOH in ethanol at room temperature (20-89%). The structures were established on the basis of NMR, IR, Single-crystal XRD, and MS. The best compound 3u had inhibitory activity (IC50 = 7.50 mu M). The synthesis, the antioxidative properties, chemical reactivity descriptors supported in Density Functional Theory (DFT), acetylcholinesterase (AChE) inhibition and their potential binding modes, and affinity were predicted by molecular docking of a number of morpholine-chalcones and quinoline-chalcone. A series of bis-chalcones are also reported. Molecular docking and an enzyme kinetic study on compound 3u suggested that it simultaneously binds to the catalytic active site (CAS) and peripheral anionic site (PAS) of AChE. Moreover, the pharmacokinetic profile of these compounds was investigated using a computational method.

A series of porphyrin-based porous polymers to support Mn heterogeneous catalysts (Mn/TFP-DPM, Mn/TFP-DPM-2, Mn/TFP-DPM-3, and Mn/TFP-DPM-4) in the selective oxidation of alcohols were designed. TFP-DPM and TFP-DPM-2 demonstrated micro/nanoscale spherical morphology, whereas TFP-DPM-3 and TFP-DPM-4 exhibited nanosheets structure. According to surface area and porosity analysis results, the specific surface areas of these catalysts were less than 300 m(2) g(-1). Thermogravimetric analysis indicated that the synthesized catalysts maintain their stability even at 300 degrees C. Catalysts Mn/TFP-DPM and Mn/TFP-DPM-3, which had the smallest and largest specific surface area among the four catalysts, respectively, were used to perform selective oxidation reaction of alcohols, with experimental results indicating that both have excellent catalytic performance. As these catalysts possess good catalytic performance despite their low specific surface area, we suggest that porphyrin-based porous polymer-supported Mn heterogeneous catalysts are promising materials for selective oxidation of alcohols.

Highly effective and safe drugs for the treatment of neuropathic pain are urgently required and it was shown that blocking T-type calcium channels can be a promising strategy for drug development for neuropathic pain. We have developed pyrrolidine-based T-type calcium channel inhibitors by structural hybridization and subsequent assessment of in vitro activities against Ca(v)3.1 and Ca(v)3.2 channels. Profiling of in vitro ADME properties of compounds was also carried out. The representative compound 17h showed comparable in vivo efficacy to gabapentin in the SNL model, which indicates T-type calcium channel inhibitors can be developed as effective therapeutics for neuropathic pain.

A novel triazine-phosphanimine polymeric organic support (TPA) was synthesized successfully by a controllable one-pot method using melamine (1,3,5-triazine-2,4,6-triamine) and trichlorophosphane (PCl3). The TPA substrate is a material incorporating P and N atoms which can coordinate with metals as a pincer ligand to stabilize them, providing an efficient heterogeneous support to prepare recyclable transition metal catalyst systems. In this study, TPA was used as support to immobilize iridium nanoparticles in the range of similar to 8 nm on its surface, resulting in the generation of a novel iridium nanocatalyst system (INP-TPA-POP). This catalyst system was characterized using different microscopic and spectroscopic techniques such as FT-IR, TEM, XPS, XRD, SEM, EDX, elemental analysis, ICP and BET analysis. The INP-TPA-POP nanocatalyst exhibited remarkable activity in reduction of aldehydes to alcohols using formic acids as reducing agent in ethanol as solvent.

A one-pot iron-catalyzed conversion of allylic alcohols to alpha-methyl ketones has been developed. This isomerization-methylation strategy utilized a (cyclopentad-ienone)iron(0) carbonyl complex as precatalyst and methanol as the Cl source. A diverse range of allylic alcohols undergoes isomerization-methylation to form alpha-methyl ketones in good isolated yields (up to 84% isolated yield).
