A newconvenientroute for direct trifluoromethylation of steroidal compounds is described. Steroidal alkenyl bromides, derived from steroidal unsaturated ketones, react with FO2SCF2CO2Me in the presence of CuI in DMF to give the corresponding trifluoromethylated steroids in good yields (70–91%).
描述了甾族化合物直接三氟甲基化的新的便利途径。衍生自甾族不饱和酮的甾族烯基溴化物,在DMF中存在CuI的情况下,与FO 2 SCF 2 CO 2 Me反应,得到相应的三氟甲基化甾族化合物,收率很高(70-91%)。
