Methods based on a ring-contraction of cyclic αβ-epoxy-ketones to give α-hydroxy-acids are used for the preparation of some 8-methyl-trans-perhydroindanone derivatives of possible interest in connection with the synthesis of 9,10-seco-steroids. They include the unsaturated ketones (10) and (22), and the hydroxy-ketones (14), (21), (46), and (49).
基于环状αβ-环氧酮的环收缩以产生α-羟基酸的方法用于制备与9,10-癸二酚的合成有关的一些可能感兴趣的8-甲基-反式-过氢氢化茚满酮衍生物-类固醇。它们包括不饱和酮(10)和(22),以及羟基酮(14),(21),(46)和(49)。
