2 and 17,17-ethylenedioxy-1,3,5(10)-estratrien-3β-ol 3 were converted into ethyl ester 1a, 2a and 3a by reaction with ethyl chloroacetate in the presence of potassium. The ethyl esters 1a, 2a and 3a on reaction with hydrazine gave hydrazides 1b, 2b and 3b, which on reaction with cyanogen bromide afforded 1,3,4-oxadiazoles 1c, 2c and 3c.
胆甾-5-烯-3β醇1,3,3-亚乙二氧基雄甾-4-烯17β醇2和17,17-亚乙二氧基-1,3,5(10) -雌三烯3β醇3被转换成乙酯1A,2A和3A通过与钾的存在下氯乙酸乙酯反应。与肼反应的乙酯1a,2a和3a得到酰肼1b,2b和3b,其与溴化氰反应得到1,3,4-恶二唑1c,2c和3c。
