Whenpyridine was used as reductive decomposing agent, the expecting cholest-4-en-3,6-dione-22-al was obtained. However, when Zn/HOAc was used to decomposethe ozonide, C-4,5 double bond was further reduced to give cholest-3,6-dione-22-al as main product. 2 For the side-chain construction of compound (1), the solid-liquid phase-transfer Wittig reaction was used. When (3-methyl-2-oxobutyl)-triphenylarsonium bromide was used as reagent, the reaction can be carried out inmild reaction condition and the yield is higher than that when phosphorane wasused.

但使用Zn/HOAc作为分解剂时,却得到其氢化产物胆甾-3, 6-二酮-22-醛;2在甾体支链引入过程中,采用固-液相转移Wittig反应的方法,用(3-甲基)-2-氧丁基三苯基溴化胂作为试剂,反应在非常温和的条件下便可完成,而且产率比传统采用膦烷的方法更高;3在对某些甾酮化合物的选择性还原反应研究时,发现在〓还原体系中,当加入某些金属离子后,反应有更好的区域选择性和立体选择性。
