A nickel(0) catalyst effectively mediates the cyclization of N-benzoyl aminals in the presence of a stoichiometric Lewis acid. This method enables preparation of a variety of isoindolinones with substitution on the benzoyl fragment and C-3 carbon. This reaction likely proceeds via an α-amidoalkylnickel(II) intermediate, which then may cyclize via either an electrophilic aromatic substitution or an
在化学计量的路易斯酸存在下,镍(0)催化剂可有效介导N-苯甲酰缩醛的环化反应。该方法使得能够制备在苯甲酰基片段和C-3碳上具有取代基的各种异吲哚啉酮。该反应可能通过α-酰胺基烷基镍(II)中间体进行,然后可以通过亲电芳族取代或插入途径进行环化。
