Abstract
A mild and highly efficient synthesis of thiazoles by the condensation of α-bromo ketones with thiourea in the presence of a catalytic amount of copper acetate at room temperature has been described. The method is applicable for a variety of aryl and alkyl α-bromo ketones. The catalyst is inexpensive, and substituted thiazoles are obtained in good yields.
