and mild carbon-sulfur coupling was realized by nickel catalysis under ball-milling conditions. The desired thioether products were generated from aryl iodides and aromatic thiol/disulfides with broad substrate scope. The Ni(i)/Ni(III) catalytic cycle was facilitated by the mechanochemistry process, thus providing an eco-friendly and time-saving strategy for the construction of the C−S bond in practical
Aqua mediated synthesis of 2-amino-6-benzothiazol-2-ylsulfanyl-chromenes and its in vitro study, explanation of the structure–activity relationships (SARs) as antibacterial agent
Multi-component reaction (MCR) involves coupling of p-bromophenol with 2-Benzothiazolethiol, malononitrile and substituted aldehydes in aqueous K(2)CO(3) as green base to synthesize 2-amino-6-benzothiazol-2-ylsulfanyl-chromenes. This multi-component reaction thus offers a higher yield and versatility in the preparation of densely functionalized oxygen heterocycles. The newly synthesized compounds were screened for their antibacterial activities against positive and gram negative pathogenic strains to bacteria. SAR analysis was performed to explore comprehensive structure activity relationships and a statistically reliable model to explain their antibacterial-activities. (C) 2010 Elsevier Masson SAS.
