Procedures are provided for selective protection of the α-carboxyl groups of aspartic and glutamic acids via the 5-oxazolidinones 2. A convenient synthesis of a differentially protected derivative of (S)-2,3-diaminopropanoic acid, 3, is described, along with examples of selective manipulation of the γ-carboxyl group of glutamic acid.
本文提供了通过 5-噁唑烷酮 2 对天冬氨酸和谷氨酸的 δ-羧基进行选择性保护的步骤。 此外,还介绍了(S)-2,3-二氨基丙酸差异保护衍生物 3 的简便合成方法,以及选择性处理谷氨酸δ-羧基的实例。
