Old problems, new ideas! The biomimetic phenol coupling of norbelladine derivatives such as 1 (Bn = benzyl) to form galanthamine (2), a drug used in the treatment of Alzheimer's disease, has been greatly improved by the use of the hypervalent-iodine oxidation reagent phenyliodine(III) bis(trifluoroacetate) (PIFA).
旧问题,新思路!通过使用高价碘氧化试剂苯基碘(III),大大改善了降贝拉定衍生物如1(Bn =苄基)的仿生酚偶联形成加兰他敏(2)(一种用于治疗阿尔茨海默氏病的药物)。双(三氟乙酸盐)(PIFA)。
