摘要

Abstract Through a [2+ 3] cycloaddition reaction, a new environmentally friendly method was developed to enable the synthesis of bioactive 1-alkyl-1H-naphtho [2, 3-d][1, 2, 3] triazole-4, 9-diones and N-aryl-2-aminomethylene-1, 3-indanediones using water as the solvent with good yields and minimum requirement of purification. This new green synthetic protocol is simple and suitable for scale-up synthesis.
