We report a one-pot synthesis of benzopyrones and tricyclic spiroketones from hydrative carbocyclization of oxodiyne substrates catalyzed by PtCl(2) and PPh(3)AuCl/AgOTf, respectively. The distinct carbocyclizations with Pt and Au catalysts stem from their altered regioselectivity in the oxo-assisted hydration of the neighboring alkyne carbons.
