Abstract

Gold-catalyzed cycloisomerizations of unsaturated precursors have become a recognized tool for the rapid construction of complex molecules.[1] While the skeletal reorganization of enyne systems has been the most intensively studied,[1c] diynes have also proved to be valuable substrates for various goldcatalyzed transformations.[2] Of particular interest, hydrative cyclizations of (Z)-hepta-4-ene-1, 6-diyn-3-yl esters led to aromatic ketones after ...
