1,2-苯二炔等价物具有独特的性质,它们可以通过迭代生成1,2-和2,3-芳炔中间体与两种亲芳基化合物反应。对这些芳炔前体的第二个离去基团进行合理修饰后,通过亲核烯反应序列开发了多米诺芳基成环方法。在不含过渡金属的条件下,可以在广泛的底物范围内实现各种苯并稠合的N-杂环骨架。
1,2-Benzdiyne equivalents possess the unique property that they can react with two arynophiles through iteratively generated 1,2- and 2,3-aryne intermediates. Upon rational modification on the second leaving group of these aryne precursors, a domino aryne annulation approach was developed through a nucleophilic-ene reaction sequence. Various benzo-fused N-heterocyclic frameworks were achievable under transition metal-free conditions with a broad substrate scope.
