  焦谷氨酸衍生物的亲电氟化：底物依赖性反应性和非对映选择性在光学活性4-氟谷氨酸合成中的应用。

  摘要：

  作为合成4-氟代谷氨酸的单一立体异构体的方法，已经研究了对映体纯的2-（吡咯烷二酮）（4）的亲电氟化反应。衍生自9的内酰胺烯醇化物与NFSi的反应导致完全非对映选择性的单氟化反应，从而生成单环反式取代的α-氟内酰胺产物21。不幸的是，21和其他与结构相关的单氟化产物的动酸度降低，使得它们对A第二次氟化。相反，在描述的标准条件下，双环内酰胺12易于二氟化，以产生α，α-二氟内酰胺24。两种类型的相关内酰胺之间反应性的差异主要归因于用于去质子化的碱和存在于吡咯烷酮底物中的保护基之间的空间相互作用的存在或缺乏。基于对21的X射线晶体结构的分析，分子模型和实验证据得出了该结论。关键中间体21和24分别转化为（2S，4R）-4-氟谷氨酸和（2S）-4，4-二氟谷氨酸。

  The title compound, a potential 'quat' auxiliary,was prepared from (S)-glutamic acid derivatives like (S)-N-Benzyl-5-methoxymethyl-2pyrrolidinone 1. Other routes starting from (S)-pyroglutamic acid in an attempt to bypass N-Aryl compounds like 1 were also tested, but. have not rendered the expected results yet.
