摘　　要： 以去氢枞酸为原料,经酰化得到酰氯,酰氯与85%(质量分数)水合肼反应制备出去氢枞酰肼,去氢枞酰肼再与5种芳香酰氯反应得N,N′-二酰基肼,其再经POCl3脱水闭环反应,合成了5种新的2-去氢枞基-5-芳基-1,3,4-二唑。研究了合成反应条件;每步收率均在75%以上。 Five novel 2-dehydroabietyl-5-aryl-1, 3, 4-oxadiazoles were synthesized by cyclization of N, N＇- diacylhydrazines with POCl3. N, N＇-diacylhydrazines were obtained via reacting dehydroabietyl hydrazine, which is prepared by dehydroabietic acid with PCl3 or SOCl2 and then 85% （mass ratio） NH2NH2·H2O, with aryl chloride. The synthesis conditions were studied, and the yield of every step is more than 75 %.
