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. Umpolung: N-heterocyclic carbene catalysis is used for the convergent and efficient transition-metal-free synthesis of 2-aryl-indoles. The interception of a highly reactive and transient aza-ortho-quinone methide by an acyl anion equivalent is central to this successful strategy. The reaction exhibits high yields and a wide scope, and it has been applied to a streamlined synthesis of a kinase inhibitor.
