Abstract

A series of 5-aryl- and 5-heteroaryl-7-carboxyl-8-hydroxyquinaldines were prepared from 5-bromo-7-methoxycarbonyl-8-benzyloxyquinaldine based on the Suzuki cross-coupling reaction using potassium organotrifluoroborates. An efficient method of deprotection of the 8-hydroxy group using a microwave-assisted­ hydrogen transfer reaction is reported.
