Dianionic enolates formed from N′-aryl urea derivatives of amino acids undergo intramolecular C-arylation by attack of the enolate anion on the N′-aryl ring, leading to a hydantoin derivative of a quaternary amino acid. In situ IR studies allow identification of four intermediates on the reaction pathway.
由氨基酸的N'-芳基脲衍生物形成的二负离子烯醇盐通过烯醇阴离子对N'-芳基环的攻击发生分子内C-芳基化反应,生成四级氨基酸的氢氨基酸衍生物。原位红外研究可以识别反应途径上的四个中间体。
