Intermolecular Gold‐Catalyzed Diastereo‐ and Enantioselective [2+2+3] Cycloadditions of 1,6‐Enynes with Nitrones

Abstract

Going for gold: The title reaction has been developed and demonstrates a wide substrate scope with respect to the 1,6-enynes and nitrones (see scheme; DCE = 1,2-dichloroethane, Tf = trifluoromethanesulfonyl). The results for the enantioselective versions are also presented.
