AuI‐Catalyzed Tandem [3,3] Rearrangement–Intramolecular Hydroarylation: Mild and Efficient Formation of Substituted Indenes

Dignified auration: The rearrangement of phenylpropargyl acetates to substituted indenes is catalyzed by [AuI(NHC)] complexes (see scheme, NHC=N-heterocyclic carbene) under extremely mild reaction conditions. This chemoselective transformation involves 1,3-migration of the acetate group and is proposed to proceed through an allene intermediate. TMS=trimethylsilyl, TBS=tert-butyldimethylsilyl.
