我们报道了一种对映体纯 (S)-4-氟组氨酸的新合成方法,该方法基于使用 Schöllkopf 双内酰氨基酸合成对 MOM 保护的 4-氟-5-溴甲基咪唑进行非对映选择性烷基化。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-氟组氨酸在所有方面与通过先前程序制备的材料相同。
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.
