annulation products reveals evidence for the participation of Nazarov cyclization. This deoxygenative cyclization is extensible to a tandemintramolecularcyclization/nucleophilic addition cascade, giving polycyclic carbo- or oxacyclic compounds with controlled stereochemistry. This new gold catalysis is applied to a short synthesis of natural compounds of the brazilane family, including brazilane, O-trimethyl-
