The formation of the condensation products obtained when pyruvic acid and aromatic amines are allowed to react, can be explained by condensation of one mole of the imine of pyruvic acid with one mole of the enamine isomer, either through the C atom or through the N atom, followed by elimination and lactonization to give a γ-lactone carboxylate or an azlactone carboxylate, which on decarboxylation give
当丙酮酸和芳香胺反应时得到的缩合产物的形成,可以解释为一摩尔丙酮酸亚胺与一摩尔烯胺异构体通过 C 原子或 N 原子缩合,然后消除和内酯化得到 γ-内酯羧酸盐或吖内酯羧酸盐,它们在脱羧时分别得到亚氨基丁内酯或吖内酯。这些环状中间体的氨解导致最终产物的形成。
