The hybrid Au(Ⅰ)/Bransted acid binarycatalyst system enables enynes to serve as latent 1,3-silyloxydienes capable of participating in the first cascade hydrosiloxylation of an enynylsilanol/asymmetric Aza-Diels-Alder reaction.A variety of polycyclic compounds bearing multistereogenic centers were obtained in yields and good enantioselectivities from the relay catalytic cascade reaction between (2-(but-3-en-1-ynyl)phenyl) silanols and glyoxylate catalyzed by the combined achiral gold complex and chiral N-triflylphosphoramide.
