Abstract
Gold-catalyzed cycloisomerization of 1,7-diyn-3,6-bis(propargyl carbonate)s leads to a highly efficient and diastereoselective synthesis of functionalized naphtho[b]cyclobutenes. A cascade sequence involving gold-catalyzed double 3,3-rearrangement, 6π-electrocyclic reaction and a decarbonylative cyclization was proposed for this reaction.
