  The chemistry of 9α-hydroxysteroids. 3. Methods for selective formation and dehydrations of 17β-cyano-9α,17α-dihydroxyandrost-4-en-3-one

  摘要：

  Two methods to produce the 17-cyanohydrin, using potassium cyanide in acetic acid/methanol or acetone cyanohydrin with aqueous sodium hydroxide, were followed with 9 alpha-hydroxyandrost-4-ene-3,17-dione, both providing 17 beta-cyano-9 alpha,17 alpha-dihydroxyandrost-4-en-3-one. The selectivity of one of these methods, that which uses acetone cyanohydrin, is not in agreement with a comparable reaction with the 9 alpha-unsubstituted androst-4-ene-13,17-dione to give the 17 alpha-cyano-17 beta-hydroxy product, as reported in the literature and confirmed by us. The 9 alpha-hydroxy and 17 alpha-hydroxy groups were used for the regioselective introduction of 9(11)- and 16(17)-double bonds by dehydrating 17 beta-cyano-9 alpha,17 alpha-dihydroxyandrost-4-en-3-one under different conditions.

  New 9-alphahydroxy steroids are prepared by the introduction of substituents on the D-ring of 9-alpha-hydroxy-androst-4-ene-3,17-dione. The resulting compounds are useful intermediates in the synthesis of corticosteroids.
