Abstract
An efficient gold(I)-catalyzed intramolecular alkoxylation/double aldol condensation cascade cyclization strategy to synthesize 2,2'-spirobi[indene] derivatives has been developed. The scope of this strategy was examined by using a batch of synthetic alkynone substrates and a possible mechanism was proposed.
