An asymmetric synthesis of the tubulin polymerisation inhibitor (S)-(-)-N-acetylcolchinol is reported based on an intramolecular biaryl oxidative coupling of a 1,3-diarylpropyl acetamide intermediate using phenyliodonium bis(trifluoroacetate) as the final step. Three syntheses of the penultimate 1,3-diarylpropyl acetamide intermediate (S)-(-)-N-[1-[3-(tert-butyldimethylsilyloxy)phenyl)]-3-(3,4,5-trimethoxyphenyl)pr
据报道,微管蛋白聚合抑制剂(S)-(-)-N-乙酰基胆酚的不对称合成是基于1,3-二芳基丙基乙酰胺中间体的分子内联芳基氧化偶联,使用苯基碘鎓双(三氟乙酸盐)作为最终步骤。倒数第二个1,3-二芳基丙基乙酰胺中间体(S)-(-)-N- [1- [3-(叔丁基二甲基甲硅烷氧基)苯基)]-3-(3,4,5-三甲氧基苯基)pr酰基的三种合成方法描述了乙酰胺,其引入立体异构中心的方式不同。
