The intramolecular hydroamination of a large variety of non-activated alkenes can be efficiently catalysed by small amounts of lithium bases, providing smoothly and in high yields the corresponding five- and six-membered ring heterocycles. Fused and bridged bicyclic amines, of varying ring sizes, can be readily prepared either by a sequential hydroamination process or by a tandem, double addition reaction
少量的锂碱可以有效地催化多种非活化烯烃的分子内加氢胺化反应,从而以高收率平稳地提供相应的五元和六元环杂环。环大小不同的熔融和桥接双环胺可以很容易地通过顺序加氢胺化工艺或串联,双加成反应制备。
