Two chiral polymers based on binaphthol(BINOL) were synthesized. The polymer can be used as a chiral inducer to coordinate with ZnEt2 to form a recoverable self-supporting catalyst, which could be used in the asymmetric catalytic reaction of alpha, beta-unsaturated ketones. The target products of high yield and good enantioselectivity(e.e. value up to 99%) can be obtained under mild conditions. The catalytic activity was not reduced significantly after 4 or 5 cycles of recovery of the recovered polymers.

In many metal catalyses, the traditional strategy of removing chloride ions is to add silver salts via anion exchange to obtain highly active catalysts. Herein, we reported an alternative strategy of removing chloride anions from ruthenium trichloride using an organic [P+-N-] zwitterionic compound via multiple hydrogen bond interactions. The resultant organic-metal hybrid catalytic system has successfully been applied to the aerobic oxidation of alcohols, tetrahydroquinolines, and indolines under mild conditions. The performance of zwitterion is far superior to that of many other common Lewis bases or Bronsted bases. Mechanistic studies revealed that the zwitterion triggers the dissociation of chloride from ruthenium trichloride via nonclassical hydrogen bond interaction. Preliminary studies show that the zwitterion is applicable to catalytic transfer semi-hydrogenation.

A new and simple method for the deoxygenation of ketones to alkanes is presented. Most substrates are reduced under mild conditions by triethylsilane in the presence of catalytic amounts of [Rh(mu-Cl)(CO)(2)](2). This system selectively provides the methylene hydrocarbons in good to excellent yields starting from acetophenones and diaryl ketones. A rapid examination of the reaction pathway suggests that the ketone is first converted into an alcohol, which then undergoes hydrogenolysis to give the alkane.

An article Catalytic Carbon-Carbon Bond Activation of Saturated and Unsaturated Carbonyl Compounds via Chelate-Assisted Coupling Reaction with Indoles WOS:000535291500049 published article about C-C ACTIVATION; RING-SLIPPAGE; H BOND; CLEAVAGE; BIOMASS; FUELS; ALKENYLATION; CHEMISTRY in [Pannilawithana, Nuwan; Yi, Chae S.] Marquette Univ, Dept Chem, Milwaukee, WI 53233 USA in 2020.0, Cited 49.0. Name: Chalcone. The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7

The chelate assistance strategy was devised to promote a highly regioselective catalytic C-C bond activation reaction of saturated and unsaturated carbonyl compounds. The cationic Ru-H complex 1 was found to be an effective catalyst for mediating the coupling reaction of 1,2-disubstituted indoles with alpha,beta-unsaturated aldehydes and ketones, in which the regioselective C-alpha-C-beta activation of the carbonyl substrates has been achieved in forming the 3-alkylindole products. The analogous coupling reaction of indoles with saturated aldehydes and ketones directly led to the C-alpha- C-beta cleavage of the carbonyl substrates in forming the 3-allcylindole products. The coupling reaction of 1,2-dimethylinole with (E)-3-nonen-2-one and 2-propanol-d(8) showed 20-22% of deuterium incorporation to both alpha- and beta-CH2 of the 3-alkylindole product. The coupling reaction of 1,2-dimethylinole with (E)-3-nonen-2-one exhibited the most significant carbon kinetic isotope effect on the alpha-carbon of the product (C-alpha = 1.046). The Hammett plot constructed from the reaction of 1,2-dimethylinole with a series of para-substituted enones p-X-C6H4CH=CHCOCH3 (X = OMe, Me, H, Cl, CF3) showed a modest promotional effect by an electron-donating group (rho = -0.2 +/- 0.1). Several catalytically relevant Ru-H species were detected by NMR from a stoichiometric reaction mixture of the Ru-H complex 1 with 1,2-dimethylindole and (E)-3-nonen-2-one in CD2Cl2. These results support a mechanism of the catalytic coupling reaction via conjugate addition of indoles to enones followed by the C-C bond activation and hydrogenolysis steps.

Novel Mannich base derivatives of glabridin were synthesized and their antiproliferative activity were performed along with our previously reported glabridin-chalcone hybrids molecules (GCHMs) against various human cell lines MDA-MB-231 (breast adenocarcinoma), HEK-293 (embryonic kidney cell line), K562 (leukemia), MCF-7 (breast adenocarcinoma), HeLa (cervix adenocarcinoma), HepG2 (hepatocellular carcinoma) and WRL-68 (hepatic carcinoma). The result showed that the glabridin significantly reduced cell proliferation with IC(50)ranges from 3.67 to 58.30 mu M against all the tested cell lines. The remarkable reduction in antiproliferative activity 2′,4′-dimethoxyglabridin and GCHMs compounds with phenolic OH groups protected by methoxy (OCH3) groups suggested that the free OH groups are essential factor for the antiproliferative activity of glabridin and its derivatives. The Mannich base derivatives of glabridin showed moderate activity IC50(2.20->95.78 mu M). Furthermore,in silicotarget identification analysis revealed that AKT1, DECR1 and NOS1 are the potential targets for glabridin and their derivatives.

In this article, a direct synthetic method for alkyl 5-arylthiophene-2-thiocarboxylates was reported. Treatment of alkyl 2-aroyl-1-chlorocyclopropanecarboxylates with excess amount of Lawesson’s reagent readily afforded alkyl 5-arylthiophene-2-thiocarboxylates in good to excellent yields under mild conditions. This cycloisomerization reaction process would be initiated by a ring-opening of the strained cyclopropane.

Reduced graphene oxide (rGO)-NaBH4 is reported as mild and efficient catalyst-system for chemo-/ regioselective reduction of structurally different aliphatic, aromatic as well as alpha,beta-unsaturated aldehydes and ketones in water. The rGO was prepared by reducing graphene oxide using Tulsi leaf extract as bio-reductant. Operational simplicity, ambient reaction condition, high yield of pure products (80-97%), no by-product formation, no use of column chromatography for purification are the salient features of the envisaged protocol. Furthermore, the recovered TRGO was recycled and reused for subsequent reductions up to five times without any loss in activity. (C) 2019 Published by Elsevier Ltd.

The complex [Cp*RuCl(COD)] reacts with LH2Cl2 (L = bis(3-methylimidazol-2-ylidene)) and LiBun in tetrahydrofuran at 65 degrees C furnishing the bis-carbene derivative [Cp*RuCl(L)] (2). This compound reacts with NaBPh4 in MeOH under dinitrogen to yield the labile dinitrogen-bridged complex [{Cp*Ru(L)}(2)(mu-N-2)][BPh4](2) (4). The dinitrogen ligand in 4 is readily replaced by a series of donor molecules leading to the corresponding cationic complexes [Cp*Ru(X)(L)][BPh4] (X = MeCN 3, H-2 6, C2H4 8a, CH2CHCOOMe 8b, CHPh 9). Attempts to recrystallize 4 from MeNO2/EtOH solutions led to the isolation of the nitrosyl derivative [Cp*Ru(NO)(L)][BPh4](2) (5), which was structurally characterized. The allenylidene complex [Cp*Ru=C=C=CPh2 (L)][BPh4] (10) was also obtained, and it was prepared by reaction of 2 with HC CC(OH)Ph-2 and NaBPh4 in MeOH at 60 degrees C. Complexes 3, 4, and 6 are efficient catalyst precursors for the transfer hydrogenation of a broad range of ketones. The dihydrogen complex 6 has proven particularly effective, reaching TOF values up to 455 h(-1) at catalyst loadings of 0.1% mol, with a high functional group tolerance on the reduction of a broad scope of aryl and aliphatic ketones to yield the corresponding alcohols.
