A parallel, versatile and efficient route to synthesis of pyrrolidinoindoline and tetrahydrofuranoindoline alkaloids from cinnamyl derivatives has been developed, featuring a domino Rh-catalyzed hydroformylationâdouble cyclization sequence. This method can be applied to the syntheses of anti-Alzheimer drugs such as physostigmine and physovenine.
已经开发出一种并行、灵活且高效的合成吡咯喲吲哚和四氢呋喃喲吲哚生物碱的新途径,该方法以肉桂基衍生物为起始材料,采用了多米诺Rh催化的氢化合物–双环化序列。该方法可应用于抗阿尔茨海默药物如物理斯的明和物理维宁的合成。
