The tetracyanoethylene catalysed methanolysis of 17 beta-acetoxy-4 beta,5 beta:6a,7 alpha-diepoxyandrostan afforded 17 beta-acetoxy-4 alpha,7 alpha-oxido-5 beta-hydroxy-6 beta-methoxyandrostane in which the methanolysis product of the 6 alpha,7 alpha-epoxide has participated in the cleavage of the 4 beta,5 beta-epoxide; the reaction is modified however by an adjacent 3 beta-hydroxy group.
