preparation of nitrile‐containing building blocks is of interest due to their utility as synthetic intermediates and their prevalence in pharmaceuticals. As a result, significant efforts have been made to develop methods to access these motifs which rely on safer and non‐toxic sources of CN. Herein, we report that 2‐methyl‐2‐phenylpropanenitrile is an efficient, non‐toxic, electrophilic CN source for
有趣的是,有效制备含腈基砌块的原因在于它们作为合成中间体的用途以及它们在药物中的普遍性。结果,已经做出了巨大的努力来开发依赖于更安全,无毒的CN来获取这些基序的方法。在此,我们报道2-甲基-2-苯基丙腈是一种有效的,无毒的,亲电子的CN来源,可通过热力学氮化和阴离子中继策略合成含腈的季铵盐中心。这种一锅法过程会导致烷基锂试剂的宝石双官能化,从而产生腈产品。
