title: Sequential Au(i)/chiral tertiary amine catalysis: a tandem C-H functionalization of anisoles or a thiophene/asymmetric Michael addition sequence to quaternary oxindoles.
abstract: 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 from diazooxindoles and nitroenynes.
