Abstract

A new convenient route 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%).
甾体分子三氟甲基化的新便捷途径
介绍了甾体化合物直接三氟甲基化的新途径。甾体烯基溴衍生自甾体不饱和酮,在DMF中有CuI存在的情况下与FO2SCF2CO2Me反应,得到相应的三氟甲基化甾体,产率很高(70-91%)。
