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

The expeditious synthesis of 2arylbenzothia/(oxa)zoles was carried out by the condensation of 2aminothiophenol/2aminophenol and diverse aryl aldehydes in presence of lt;em gt;Acacia concinna lt;/em gt; 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.
