Studying the behaviour of 1–3 dipolar additions of nitrile-oxides to dipolarophilic steroid systems, the relative reactivity of the double bond CC (endo or exocyclic) and of the nitrile-group has been examined, using two unsaturated and a saturated one nitrile as control. The CN group has been found more reactive than the CC bond. The physico-chemical properties of 1,2,4 oxadiazoles obtained and
研究了对偶极亲和性甾体系统的1–3个偶极氮氧化物的偶极加成行为,研究了双键C aC(内环或环外)和腈基的相对反应性,使用了两个不饱和和饱和的一个腈作为对照。已经发现CN基团比CC键更具反应性。讨论了1,2,4恶二唑和中间体的理化性质。
