to serve as latent 1,3-silyloxydienes capable of participating in the first cascadehydrosiloxylation of an enynyl silanol/asymmetric Diels-Alder reaction. A variety of polycyclic compounds bearing multistereogenic centers were obtained in high yields and excellent enantioselectivities from the relaycatalyticcascadereaction between (2-(but-3-en-1-ynyl)phenyl) silanols and quinones catalyzed by the

Abstract The hybrid gold(I)/Brønstedacid binary catalyst system enables enynes to participate in an asymmetric relaycatalyticcascade intramolecular hydrosiloxylation and asymmetric hetero-Diels–Alder reaction with fluorenyl glyoxylate. The hybrid gold(I)/Brønstedacid binary catalyst system enables enynes to participate in an asymmetric relaycatalyticcascade intramolecular hydrosiloxylation and
