Efficient synthesis of (S)-(+)-lycoperdic acid has been achieved by use of the stereoselective hydroxylation of the enolate derived from the bicyclic lactam 3 with the molybdenum oxidizing reagent, MoOPH (MoO5·Py·HMPA, oxodiperoxymolybdenum(pyridine)(hexamethylphosphoric triamide)), as a key step.
(S)-(+)-甘油高碘酸的有效合成已通过使用双环内酰胺3衍生的烯醇化物与钼氧化剂MoOPH(MoO 5 ·Py·HMPA,氧二过氧钼(吡啶))的立体选择性羟基化来实现(六甲基磷酸三酰胺))作为关键步骤。
