are assuming increasing importance as probes of biological function and enzyme mechanism. We now report a new, flexible route to enantiomerically pure L-4,4-difluoroglutamic acid that exploits the addition of difluorinated nucleophiles to configurationally stable alpha-aminoaldehydes. Conversion of the difluorinated adducts to L-4,4-difluoroglutamic acid can be accomplished in three steps by Barton-McCombie
氨基酸的含氟衍生物作为生物学功能和酶机制的探针正变得越来越重要。现在,我们报告了一条新的,灵活的途径,可生产对映体纯的L-4,4-二氟谷氨酸,该化合物利用向结构稳定的α-氨基醛中添加二氟亲核试剂。二氟化加合物向L-4,4-二氟谷氨酸的转化可以通过Barton-McCombie脱羟基化和酸水解在三个步骤中完成。
