Abstract

(Chemical equation presented) A great combination: A putative indolyl-substituted vinyl gold species generated in situ from AuCl/AgOTf catalyzed the title transformation. Under these reaction conditions, indenyl-fused and 2,3-disubstituted indole derivatives were produced in good to excellent yields of up to 94% (see scheme). © 2010 Wiley-VCH Verlag GmbH & Co.
