A biomimetic enantioselective transamination of α-keto ester derivatives can be realized under mild conditions by using chiral quaternary ammonium arenecarboxylates in the absence of base additives. The corresponding α-amino acids can be used as versatile intermediates for further synthetic transformations that furnish chiral pyrrolidine and octahydroindolizine derivatives.
α-酮酯衍生物的仿生对映体选择性氨基转移可以在温和的条件下,通过在不存在碱添加剂的情况下使用手性季铵芳烃羧酸酯来实现。相应的α-氨基酸可用作用于进一步的合成转化的通用中间体,其提供手性吡咯烷和八氢吲哚嗪衍生物。
