Abstract

Abstract: A novel methodology for the synthesis of 2-benzoylbenzothiazoles and 2-benzylbenzothiazoles through FeCl3·6H2O catalyzed, air oxidized tandem process from commercially available 2-aminothiophenols and phenylacetaldehydes by using an ionic liquid as both reaction medium and co-catalyst was developed.

Abstract

Abstract: An efficient, practical and environmentally benign synthesis of 2-substituted benzothiazoles was developed through RuCl3-catalyzed oxidative condensation of 2-aminothiophenol with aldehyde in ionic liquid by using air as the oxidant. With this procedure, a series of 2-substituted benzothiazoles and benzothiazole/pyrimidine nucleoside hybrids with antimicrobial activities were efficiently prepared from easily accessible starting materials.

Abstract

Abstract: An efficient and environmentally benign synthesis of 1,2-allenic ketones via RuCl3-catalyzed oxidation of homopropargyl alcohols in ionic liquid with tert-butyl hydroperoxide (TBHP) as the oxidant was reported for the first time. With its reasonable efficiency and green nature, this oxidation provides a novel alternative route to 1,2-allenic ketones. [Copyright &y& Elsevier]
