Gold(I)-Catalyzed Enantioselective Synthesis of Benzopyrans via Rearrangement of Allylic Oxonium Intermediates
[Image: see text] The first transition metal-catalyzed asymmetric carboalkoxylation reaction of propargyl esters is described. The (R)-MeO-DTBM-BIPHEP(AuCl)(2)-catalyzed reactions allows for the construction of benzopyrans containing quaternary stereocenters with excellent enantioselectivity. Experi...
