We report a one-pot synthesis of benzopyrones and tricyclic spiroketones from hydrative carbocyclization of oxodiyne substrates catalyzed by PtCl2 and PPh3AuCl/AgOTf, respectively. The distinct carbocyclizations with Pt and Au catalysts stem from the

We report a one-pot synthesis of tetracyclic ketones via PtI2-catalyzed hydrative cyclization of trialkyne functionalities. These triyne substrates bear an electron-rich aryl group at the outer alkyne to direct the initial hydration occurring at the

This work investigates the feasibility of thermal and catalytic cyclization of 6,6-disubstituted 3,5-dien-1-ynes via a 1,7-hydrogen shift. Our strategy began with an understanding of a structural correlation of 3,5-dien-1-ynes with their thermal cycl
