摘要

ABSTRACT A highly efficient, simple and rapid method for the preparation of various 2- aminobenzoxazoles and other benzoxazole derivatives using a catalytic amount of poly (ethylene glycol)-bound sulphonic acid (PEG-SO 3 H) is described. PEG-SO 3 H is found to be economical and reusable catalyst with low catalytic loading. The percentage yield was found to be satisfactory, experimental set-up and purification of final products is facile and ...
