We report a new synthesis of enantiomerically pure (S)-4-fluorohisitidine based on diastereoselective alkylation of MOM-protected 4-fluoro-5-bromomethyl imidazole using the Schöllkopf bis-lactim amino acid synthesis. Improvements in procedures for preparation of key intermediates are also described. (S)-4-Fluorohisitidine prepared by this new method was identical in all respects to material prepared by previous procedures.
我们报道了一种基于使用朔尔科普夫双内酰胺氨基酸合成法对甲氧基甲基(MOM)保护的4-氟-5-溴甲基咪唑进行非对映选择性烷基化反应来合成对映体纯的(S)-4-氟组氨酸的新方法。还描述了关键中间体制备程序的改进。通过这种新方法制备的(S)-4-氟组氨酸在各方面均与以前方法制备的材料相同。
