摘要 目的优化苯磺顺阿曲库铵的合成工艺。方法以3,4-二甲氧基苯乙胺和3,4-二甲氧基苯乙酸为原料,依次经酰化、脱水环化及还原反应制得四氢罂粟碱。采用半量拆分法,以D-(+)-二对甲基苯甲酰酒石酸为拆分剂,将四氢罂粟碱外消旋体拆分得到R-四氢罂粟碱。再通过麦克尔加成,氮甲基化等反应得到苯磺顺阿曲库铵。结果目标产物的结构通过质谱、核磁共振氢谱和碳谱进行了确证,纯度经HPLC检测为99.18%,总产率为24.79%。结论优化后的合成工艺具有反应条件温和、操作简便和反应产率高的优点,为工业化生产提供了参考。 OBJECTIVE To optimize the synthesis process of cisatracurium besylate.METHODS Using 3,4-dimethoxyphenethylamine and(3,4-dimethoxyphenyl)acetic acid as starting material,tetrshydropapaverine was prepared by acylation,dehydration cyclization and reduction reaction.The semi-quantitative method was used to obtain R-tetrshydropapaverine with(+)-Di-1,4-toluoyl-D-tartaric acid as resolving agent.Then cisatracurium besylate was synthesized by michael addition reaction and methylation reaction.RESULTS The structure of the target product was confirmed by MS,1H-NMR,and 13C-NMR.The HPLC indicated that the purity of product was 99.18%,and the total yield was 24.79%.CONCLUSION The optimized process have the characteristics such as short reaction time,simple operation and highly yield,which provide significant information and basis for industrial production.
