Abstract

A palladium-catalysed, phosphine-free, direct arylation of 4-phenoxyquinolines, in air is described. Using an intramolecular approach, the ring-closed products are formed in yields of up to 95 %. This approach allows access to a range of benzofuroquinolines. An array of functional groups on both the quinoline and phenoxy rings are tolerated.
