chemistry, and therefore, novel and efficient approaches to their synthesis are in high demand. Among indoles, 2‐aryl indoles have been described as privileged scaffolds. Advanced herein is a straightforward, practical, and transition‐metal‐free assembly of 2‐aryl indoles. Simply combining readily available 2‐fluorotoluenes, nitriles, LiN(SiMe3)2, and CsF enables the generation of a diverse array of indoles
吲哚是药物化学中必不可少的杂环,因此,迫切需要新颖有效的合成方法。在吲哚中,2-芳基吲哚被描述为特权支架。本文的高级内容是一种简单,实用且不含过渡金属的2-芳基吲哚化合物组装方法。简单地将容易获得的2-氟甲苯,腈,LiN(SiMe 3)2和CsF结合起来,就可以生成各种各样的吲哚(38例,产率48-92%)。可将一系列取代基引入吲哚骨架的每个位置(C4至C7,以及C2处的芳基),以提供进一步处理的方法。
