amidination/N-alkylation reaction of amines by alcohols has been developed. For the first time, nitriles have been identified as an efficient and benign water acceptor reagent in N-alkylation. Notably, the procedure tolerates a series of functional groups, such as methoxyl, halo, vinyl and hetero groups, providing a convenient method to construct different substituted diamino compounds, 15N labeled
已经开发了碱通过醇介导的胺的级联酰胺化/ N-烷基化反应。首次在N-烷基化中将腈鉴定为有效且良性的水受体试剂。值得注意的是,该方法可耐受一系列官能团,例如甲氧基,卤素,乙烯基和杂基,为构建不同的取代的二氨基化合物,15 N标记的胺提供了便利的方法,并且可以按比例放大至1 mol规模,可提供138.7 g一锅即可获得高收率的所需产品。机理研究为t -BuOK促进胺与腈酰胺化提供了有力的证据。
