(−)-Erycibelline, the dihydroxynortropane alkaloid isolated from Erycibe elliptilimba Merr. et Chun., was synthesized using a cyclic nitrone as advanced intermediate, wherein the key step was the SmI2-induced intramolecular reductive coupling of cyclic nitrone with aldehyde which resulted in good yield and stereoselectivity.
(-)-Erycibelline,从Erycibe elliptilimba Merr分离出的二羟基降冰片烷生物碱。等人使用环硝酮作为高级中间体合成了其中的关键步骤,其中关键步骤是SmI 2诱导的环硝酮与醛的分子内还原偶联,从而获得了良好的收率和立体选择性。
