Acacia concinna pod catalyzed synthesis of 2-arylbenzothia/(oxa)zole derivatives

Abstract

The expeditious synthesis of 2-aryl-benzothia/(oxa)zoles was carried out by the condensation of 2-aminothiophenol/2-aminophenol and diverse aryl aldehydes in presence of <em>Acacia concinna</em> as a biocatalyst under microwave irradiation. The catalytic process is associated with excellent yields, greener reaction conditions and the environmentally friendly microwave technique which are the striking features of the present protocol.
