Facile and high yielding Suzuki and Stille cross-coupling reactions of 3-br
omo-quinoxalin-2-ylamines were developed to synthesize a variety of novel a
nd diversely functinalized 3-aryl and 3-heterocyclic quinoxalin-2-ylamines.
The preparation of the substrates and the remarkable impact that substitue
nts have on the regiochemical outcome are discussed. (C) 1999 Elsevier Scie
