2′,2′-trichloroethyl 2-bromo-2-(3,4-dimethoxyphenyl)acetate in seven steps with an overall yield of 11%. Ningalin C is synthesized from 1-[2-(3,4-dimethoxyphenyl)ethyl]-3,4-bis-(3,4-dimethoxyphenyl)-1H-pyrrole and methyl 2-diazo-2-(3,4-dimethoxyphenyl)acetate in five steps with a total yield of 19%.
从3-(3,4-二甲氧基苯基)丙酮酸,2-(4-甲氧基苯基)乙胺和2',2',2'-三氯乙基2-溴-2-(3,4-二甲氧基苯基)乙酸酯中获得紫酮七个步骤,总产率为11%。Ningalin C由1- [2-(3,4-二甲氧基苯基)乙基] -3,4-双-(3,4-二甲氧基苯基)-1 H-吡咯和甲基2-重氮-2-(3,4)合成分五个步骤合成乙酸-二甲氧基苯基酯),总产率为19%。
