【摘要】 2-苯基-1,2,3-连三唑-4-甲酰肼（1）与芳酸在POCl₃催化下得到6种新的2-芳基-5-（2’-苯基-1’,2’,3’-连三唑-4’-基）-1,3,4-噁二唑（2）。1与羰基化合物缩合得到相应的酰腙（3）,在Ac₂O作用下环化成2-取代基-3-乙酰基-5-（2’-苯基-1’,2’,3’-连三唑-4’-基）-1,3,4-噁二唑啉（4）。化合物的结构经元素分析,IR,¹H NMR和MS确证。更多还原

【Abstract】 By the condensation of 2 - Phenyl - 1,2,3- triazole - 4 - formyl hydrazide (1) with substituted benzoic acids in the presence of phosphorus oxychloride,six novel 2 - Aryl - 5 - (2’ - Phenyl - 1’ ,2’ ,3’ - triazole -4’ -yl) - 1,3,4- oxadiazoles (2) were obtained. Reaction of acid hydrazide (1) with keto compounds gives corresponding hydrazones (3),which could be readily converted to their congener oxadiazolines (4) in good yields by treatment with Ac2O. Their structures were established by elemental analysis, IR,1H NMR and MS spectroscopy.更多还原
