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.

Inexpensive copper catalysts allow for efficient syntheses of N-aryl-, N-acyl-, or N-H-(aza)in-doles starting from ortho-alkynylbromoarenes. The broad scope of this domino N-arylation/hydro-amin(d)ation process is highlighted by the synthesis of highly fu

Potassium [1-(tert-butoxycarbonyl)-1H-indol-2-yl]trifluoroborate (1) was used in Suzuki-type coupling reactions. First, the best coupling conditions were assessed using bromobenzene as the electrophile. Then, 1 was successfully coupled with various aryl a
