A simple, convenient and general method, exhibiting good functional group tolerance, is described for the synthesis of N- and N,N-disubstituted amidines by the reaction of primary carboxamides with amines mediated by trimethylaluminium (AlMe3). Subsequent reaction of the indole systems with primary carboxamides in the presence of AlMe3 gives exclusively the C-3 substituted imine product.
描述了一种简单、方便和通用的方法,具有良好的官能团耐受性,用于通过伯酰胺与三甲基铝 (AlMe3) 介导的胺反应合成 N-和 N,N-二取代脒。在AlMe 3 存在下吲哚体系与伯甲酰胺的后续反应仅产生C-3取代的亚胺产物。
