The Serini reaction of 16α-alkyl (or phenyl)-1β,17β-dihydroxysteroid monoacetates 5 and 10 gave stereospecifically 16β-substituted steroids 6 and 111 in good yields. This rearrangement was shown to proceed through 1,2 hydride shift. It was found that under the same reaction conditions, 16α-vinyl-16β,17β-diol 17-acetate 5c rearranged into Z-16-ethylidene compound 24 via 1,4 hydride shift.
16α-烷基(或苯基)-1β,17β-二羟基类固醇单乙酸酯5和10的Serini反应以良好的产率产生了立体定向的16β-取代的类固醇6和111。该重排显示通过1,2氢化物转移进行。发现在相同的反应条件下,16α-乙烯基-16β,17β-二醇17-乙酸酯5c通过1,4-氢化物转移而重排为Z -16-亚乙基化合物24。
