A new access to benzofulvenes bearing an indol-3-yl substituent at C-2 has been developed. Treatment of 3-propargylindoles possessing an additional hydroxy group at the other propargylic position with a cationic gold(I) complex triggers a tandem 1,2-indole migration/aura-iso-Nazarov cyclization/elimination sequence that takes place under mild conditions.
