【Abstract】 Imidazole-4,5-dicarboxylic acid, which was got from tartaric acid by cyclization, was esterified, hydrazinnolized and then condensated with aroyladehydes in glacial acetic acid to synthesize seven new imidazole-4,5-diacylhydrazones in mild condition with high yield, especially the condensation reaction was finished very quickly(from several seconds to several minutes) and the work-up was simple too. These new compounds were characterized by elementary analysis, IR, 1H NMR and 13C NMR.更多还原
