摘要: A clean, efficient and catalyst-free multicomponent domino reaction of arylglyoxals, cyclic 1,3-dicarbonyls thioamides in aqueous media under microwave conditions is reported. wide variety trisubstituted thiazoles can be synthesized good to very yields using this green protocol. The salient features methodology are: reaction, water as medium, short time, yields, use heating, no harmful by-products.
