Abstract Despite several reported procedures for coupling alkyl halides and 5-oxoproline esters (pyroglutamate derivatives), no general method has been described. The reaction of pyroglutamate with sodium hydride, in anhydrous THF in the presence of the halide, provides this general and practical alkylation method. Alkylation under phase transfer conditions is a useful, but less general, alternative
摘要 尽管有几种用于偶联烷基卤化物和 5-氧代脯氨酸酯(焦谷氨酸衍生物)的报道程序,但尚未描述通用方法。在卤化物存在下,焦谷氨酸盐与氢化钠在无水 THF 中的反应提供了这种通用且实用的烷基化方法。在相转移条件下烷基化是一种有用但不太通用的替代方法。
