A convergent and efficient transition‐metal‐free catalytic synthesis of 2‐aryl‐indoles has been developed. The interception of a highly reactive and transient aza‐ortho‐quinone methide by an acyl anion equivalent generated through N‐hetereocyclic carbene catalysis is central to this successful strategy. High yields and a wide scope as well as the streamlined synthesis of a kinase inhibitor are reported
已经开发了一种收敛且高效的无过渡金属催化合成 2-芳基-吲哚。通过 N-杂环卡宾催化产生的酰基阴离子等价物拦截高反应性和瞬态的氮杂邻苯醌甲基化物是这一成功策略的核心。报告了激酶抑制剂的高产率和广泛的范围以及简化的合成。
