The first pKa scales for chiral thiourea catalysts and their correlations with the corresponding parameters of the bifunctional catalysis was reported. Twenty chiral thiourea-tertiary amine compounds were synthesized and electronic variations w

A simple alkylthiourea was found to be an effective catalyst for the Michael addition reaction of 3-substituted oxindole to nitroolefins. A number of 3,3′-substituted oxindole derivatives, which have two vicinal quaternary-tertiary chiral centers were syn
