2-Aminothiazole derivatives are widely used structural motifs in medicinal chemistry due to their broad application in drug development. Herein we demonstrate a novel one-step method for the synthesis of 2-aminothiazole derivatives from the corresponding isothiocyanates via thiourea formation followed by cycloisomerisation in an intramolecular thia-Michael fashion. This method is very mild, simple
