The kinetic and thermodynamic features of indole N1‐ and C6‐alkylation reactions with (aza‐)quinone methides have been studied. The electrophilic reactivity of these quinone methides have also been compared for the first time by both experiments and DFT calculations. The indole N1‐alkylation is typically kinetically favorable, but the C6‐alkylation is more thermodynamically favorable. With suitable
研究了
吲哚N1-和C6-烷基与(氮杂)醌甲基化物反应的动力学和热力学特征。还通过实验和DFT计算首次比较了这些醌甲基化物的亲电反应性。
吲哚的N1-烷基化反应通常在动力学上是有利的,而C6-烷基化反应在热力学上更有利。在适当的条件下,可以高效高效地实现C6-烷基化。在这些醌甲基化物中,反应性从aza-p-QMs增加到o-QMs。结果不仅提供了一系列有价值的三芳基
甲烷的途径,而且还指导了这些通用型亲电试剂新反应的未来发展。
