Abstract
Acetonitrile and triethyl amine has been identified as green solvent and base catalyst or the 1 multicomponent synthesis of 5-arylidine-2-(methylthio)-thiazolones (4) in good to excellent yields (83-97%) starting from rhodanine (1), substituted aryl aldehyde (2) and iodomethane (3) by using microwave irradiation method. Present protocol offers advantages of short reaction time, simple workup, and high yields of products.
