  A novel method for stereospecific generation of either C-20 epimer in steroid side chains by palladium-catalyzed hydrogenolysis of C-20 allylic carbonates

  摘要：

  Both natural and unnatural epimers at C-20 in a steroid side chain can be generated stereospecifically by the palladium-catalyzed hydrogenolysis with triethylammonium formate of C-20 (Z) or (E) allylic carbonates, respectively.
