We report an unprecedented sequential Au(i)/bifunctional tertiary amine catalysis, which enables a tandem C–H functionalization of weak nucleophiles (anisoles or thiophenes) and asymmetric Michael addition for the highly enantioselective synthesis of quaternary oxindoles.

Catalytic Asymmetric

A series of novel chiral bifunctional tertiary amine–thioureas based on spirobiindane were designed and synthesized as organo­catalysts. One of these catalysts was shown to promote the asymmetric Michael addition reaction of 1,3-diphenylpropane-1,3-dione to nitro­olefins, affording the desired products in good yields (up to 95%) and enantioselectivities (up to 98% ee).
