Facile One-Pot Procedure for the Synthesis of 2-Aminothiazole Derivatives
摘要:
A facile, efficient synthesis of 2-aminothiazole derivatives by the reaction of easily available aromatic methyl ketones with thiourea/N-substituted thioureas in the presence of copper(II) bromide was developed. The reaction underwent a one-pot alpha-bromination/cyclization process.

A simple, efficient, single step and environmentally benign synthesis of 2-aminothiazoles is described in this paper. This green protocol was catalyzed by recyclable solid supported Nafion-H using polyethylene glycol-water solvent system with improved efficiency and reduced waste production.[GRAPHICS].
