✦ Synopsis


We report a new synthesis of thiazoles froma cyclocondensationreactionbetweendimethyl N-(ethoxycarbonylmethyl)iminodithiocarbonate (EMIC), carbon disulfide and alkylation of intel mediate thiazole-Z-thiolate with alkyl halides.

We have recently studied the reaction of carbanion fromdimethyl N-(ethoxy carbonylmethyl)iminodithiocarbonate (EMIC) 1,2 2,3 with aromatic aldehydes
