The gold(I)-catalyzed cyclization reactions of N-(3-Iodoprop-2-ynyl)-N-tosylaniline derivatives afford iodinated 1,2-dihydroquinoline derivatives. Two regioisomer products are obtained, one derived from direct cyclization and other involving concomitant 1,2-iodo migration. The ratio of these two products can be modulated by a proper ancillary ligand in the gold catalyst. (C) 2010 Elsevier B.V. All rights reserved.
