摘要

An efficient and mild route to a series of benzo [b] thiophenes, benzo [b] furans, and dibenzofurans through gold-catalyzed benzannulation of 1-heteroarylalka-2, 3-dienyl acetates was developed. Two possible pathways of this reaction involving gold carbene and aryl gold intermediates have been proposed on the basis of mechanistic studies.
