16α,17α-Oxido-16β-methyl-△5-3β-ol-20 one(Ⅱ)was reduced to a mixture of compounds Ⅶa,Ⅷa and Ⅸ by lithium aluminium hydride.Structures of these compounds were proved by degradation reactions.The C20-configurations were established by comparisons of relative reaction rates,molecular model consideration,and molecular rotation differences of the related compounds.
