A chiral gold(I) complex-catalyzed highly regio- and enantioselective azo hetero-Diels-Alder reaction has been developed. The chiral gold(I) complex acting as a Lewis acid exhibits high efficiency in the activation of urea-based diazene dienophiles. Moreover, this chiral goldcatalyst also rendered a cascade intramolecular enyne cycloisomerization/asymmetric azo-HDA reaction.
