  Reaction of 3β-chloro-5α,6α-epoxysteroids with trifluoroacetic acid

  摘要：

  It has been established that on the interaction of the 5 alpha, 6 alpha-eponysteroids (1a-c) with trifluoroacetic acid in chloroform the 6-trifluoroacetates of the 5 alpha,6 beta-diols (2a-c) are formed in high yield. The alkaline hydrolysis of the trifluoroacetates (2a-c) leads to the corresponding diols (3a-c).

  It has been established that the reaction of 3 beta-chloro-Delta(5)-steroids with trifluoroperacetic acid forms not only the 5 alpha,6-peroxides (3a,d), but also the 5 alpha,6 beta-diols (5a,b,d) and their 6-trifluoroacetates.
