dehydropipecolinic acid—revealed that these compounds undergo rapid hydrolysis in neutral aqueous medium, via the imine tautomers, even when the corresponding esters and sodium salts exist as the enamine tautomers. This is true even for dehydropipecolinic acid which had been reported to be stable for 10–18 h in dilute aqueous neutral solution.
对α,β-不饱和α-氨基酸-脱氢缬氨酸,脱氢苯丙氨酸和脱氢胡椒碱酸的研究表明,即使这些化合物以亚胺互变异构体形式存在于中性水性介质中,也会通过亚胺互变异构体快速水解。烯胺互变异构体。甚至对于据报道在稀的中性水溶液中可稳定10–18小时的脱氢哌嗪酸也是如此。
