The reaction of cyclopropyl phenyl ketone 1-ureidoethylidenehydrazones 14 with a mixture of tri-phenylphosphine, carbon tetrachloride, and triethylamine provides a general route to N-α-styrylcyclo-propane-5-phenylamino-1,2,4-triazoles 17 via the thermal reaction of the expected azinocarbodiimide intermediates 15, and the oxidation of 17 with 3-chloroperoxybenzoic acid affords 1,2,4-triazole substituted
环丙基苯基酮1- ureidoethylidenehydrazones 14与三苯基膦,四氯化碳的混合物的三乙胺反应,并提供给的一般途径Ñ -α-styrylcyclo丙烷-5-苯氨基-1,2,4-三唑17经由该预期的叠氮碳二亚胺中间体15的热反应和用3-氯过氧苯甲酸的17的氧化直接得到1,2,4-三唑取代的γ-丁内酯23。
