The determination of the structure of the intermediate in the Bucherer-Bergs reaction (the transformation in aqueous solution of an aldehyde into the corresponding amino-acid via the hydantoin) showed that this reaction involved the formation of α-aminonitrile carbamate. The slow formation of the carbonic anhydride from the carbonate buffer limited the formation of that main intermediate which was
Bucherer-Bergs反应中中间体结构的确定(醛在乙醛水溶液中通过乙内酰脲转化为相应的氨基酸)表明该反应涉及α-氨基腈氨基甲酸酯的形成。由碳酸盐缓冲液缓慢形成碳酸酐,限制了与α-氨基腈处于平衡状态的主要中间体的形成。氨基甲酸酯的稳定性相对于pH的变化主要取决于混合物中溶解的CO 2浓度,还取决于由α-氨基腈降解形成的产物的平衡形成,即氨基二腈和氰醇。
