未活化的氨基烯烃在温和条件下进行FeCl 3催化的分子内氢胺化反应,以良好的产率得到吡咯烷和哌啶,而不需要排除空气和水分。值得注意的是,含有卤化物部分的氨基烯烃是容许的。该方法适用于合成二氮杂-和氧氮杂螺双环化合物(VIII)和(X)。
Unactivated aminoolefins react under mild conditions in a FeCl 3-catalyzed intramolecular hydroamination reaction to afford pyrrolidines and piperidines in good yields, without the need to exclude air and moisture. Remarkably, aminoolefins containing halide moieties are tolerated. The method is applicable to the synthesis of diaza-and oxazaspirobicyclic compounds (VIII) and (X).
