We describe a facile strategy for building enantioenriched fluoroalkyl-substituted syn-diamines by the asymmetric gem-difunctionalization of 2,2,2-trifluorodiazoethane, which could be efficiently converted to a series of fluoroalkyl-substituted structures. The proposed key intermediate is an ammonium ylide generated from 2,2,2-trifluorodiazoethane, and its reactivity was further explored by DFT calculations
我们描述了一种通过2,2,2-三氟重氮乙烷的不对称宝石-双官能化来构建对映体富集的氟烷基取代的顺式二胺的简便策略,它可以有效地转化为一系列氟烷基取代的结构。拟议的关键中间体是由2,2,2-三氟重氮乙烷生成的叶立铵,其反应性通过DFT计算得到了进一步探索。
