炔诺酮醋酸酯合成的工艺改进

    Improved Synthesis of 19-Norehisterone Acetate

    • 摘要: 以炔诺酮为原料,醋酐为酰化剂,使17—羟基酯化成炔诺酮醋酸酯。实验中发现在水汽蒸馏时加入醋酸钠可抑制炔诺酮醋酸酯的水解。经熔点、红外光谱以及氢核磁共振光谱均证明此化合物为炔诺酮醋酸酯。

       

      Abstract: 19-Norethisterone acetate is prepared by heating 19-norethisterone with Ac2O. It was wise to add NaAc in the operation of steaming distillation, to let it become a buffer pair with HAc and to prevent 19-norethis-terone acetate from hydrolyzing. The struct
