an efficient synthesis of polyhydroquinoline derivatives was reported via four-component coupling reactions of aldehydes, 1,3-dicarbonyl ketones (dimedone or 1,3-cyclohexanedione), ethyl acetoacetate or methyl acetoacetate and ammonium acetate in the presence of a catalytic amount of nanocrystalline tio2 under solvent free conditions. the reported method is mild, rapid and has the advantages su...

Abstract In the last decade, interactions among histone modifications and DNA methylation their effect on structure, i.e., chromatin state, have been identified as key mediators for maintenance of cell identity, defined epigenetic memory. this paper, we determine how positive feedback loops generated by auto- cross-catalysis repressive affect temporal duration identity. To end, conduct a stocha...

background: auto-acupressure is an effective pain treatment method in various conditions. the aim of this study was determining of auto-acupressure efficacy in patients with migraine. methods: 48 voluntary subjects were selected using convenience sampling method and randomized into two, auto-acupressure (25 patients) and control (23 patients), groups.  intervention for the treatment group inclu...

A novel strategy for highly efficient utilization of chiral ammonium salt catalysts has been described in this paper. Three kinds of catalytic functions including iminium catalysis, enamine catalysis, and acid catalysis of chiral ammonium salt catalysts, have been achieved in the enantioselective reduction and alkylation reaction of α,β-unsaturated aldehydes with alcohols.

The principles that underlie enzyme catalysis also apply to energy coupling processes. A comparison is made between a kinase system that mediates the phosphorylation of glucose by ATP (hexokinase), as the prototype for enzymic catalysis, and the mitochondrial electron-transfer complexes, as the prototypes for energy coupling systems. Induced polarization of chemical bonds and charge separation ...

Regioselective difunctionalization of alkenes has attracted significant attention from synthetic chemists and has the advantage of introducing diverse functional groups into vicinal carbons of common alkene moieties in a single operation. Herein, we report an unprecedented intermolecular atom transfer thiosulfonylation reaction of alkenes by combining gold catalysis and visible-light photoredox...
