Herein, we present a novel one-pot aqueous reaction for the synthesis of 2-iminothiazolines and 2-aminothiazoles using isocyanides, amines, sulfur, and 2′-bromoacetophenones. The three-component preparation of thioureas is followed by the one-pot cyclization leading to the heterocyclic product. This efficient and mild procedure features excellent step- and atom-economy and enables the chromatography-free preparation of diversely substituted 2-iminothiazoline and 2-aminothiazole derivatives.
