  • Publication number: 20120214987
    Abstract: The invention relates to processes for preparing 3?-O-linked steroids including 3?-O-linked-androst-5-ene steroids and 3?-O-linked-5a-androstane steroids. In one process a 3?,4?-epoxy androst-5-en-17-one is predominately reduced at the epoxy moiety wherein reduction of the 3?,4? epoxy functional group occurs preferentially at position C4 with retention of configuration at position C3 to provide a 3?-O-linked-androst-5-ene steroid. In another process, conditions are provided for inversion of configuration of a 3?-hydroxy-androst-5-ene steroid by the Mitsunobu reaction to provide a 3?-O-linked-androst-5-ene steroid with reduced amounts of 3?,5?-cycloandrostane side-product impurities.
