A general method to synthesize functionalized allyl α-amino acid derivatives through an irreversible oxy-2-azonia-Cope rearrangement is reported. In the presence of AlCl3, the reaction of imino ethyl glyoxalates with various β,γ-unsaturated ketones furnished the corresponding allyl α-amino acid derivatives. The key to the success of this method is the amide bond formation, which makes the rearrangement
报道了通过不可逆 oxy-2-azonia-Cope 重排合成功能化烯丙基 α-氨基酸衍生物的一般方法。在AlCl3存在下,亚氨基乙醛酸乙酯与各种β,γ-不饱和酮反应生成相应的烯丙基α-氨基酸衍生物。这种方法成功的关键是酰胺键的形成,这使得重排不可逆。该反应系统构成了合成不寻常的烯丙基甘氨酸衍生物的新策略,这些衍生物是有价值的合成中间体。还进行了该反应的有效且操作简单的三组分版本。
