Highly regioselectivesynthesis of 2-acyl-4-(het)arylthiazoles and thioethers by the reaction between α-oxothioamides and α-bromoketones in the absence of base in DMF and in the presence of triethylamine in acetonitrile, respectively, has been reported. This thiazolesynthesis is an important extended work of the Hantzschthiazolesynthesis, which overcomes the drawbacks of earlier reported methods
