A process for the preparation of chiral 3-aminopyrrolidine and analogous bicyclic derivatives from dihydroxy olefins by treatment with titanium isopropoxide, an optically active tartrate ester and tert-butyl hydroperoxide, followed by subsequent alkylation of the intermediate with an alkyl or alkenyl magnesium halide, then pyrrolidine ring formation by condensation with an arylmethylamine, subsequent chiral replacement of a ring hydroxyl group with an amino group with further protection thereof, optional additional substitution closing of the second ring, and hydrogenolysis to remove a ring-nitrogen protecting group.
通过与异丙氧基钛、光学活性酒石酸酯和叔丁基过氧化氢处理二羟基烯烃,然后通过与烷基或烯基镁卤化物进行中间体烷基化,随后通过与芳基甲基胺缩合形成吡咯烷环,随后通过将环羟基替换为氨基并进一步保护,可选地进行第二环的附加取代封闭,最后通过氢解去除环氮保护基,制备手性3-氨基吡咯烷及类似的双环衍生物的制备方法。
