The bifunctional quinine-derived thiourea catalyst 14 was found to catalyze the direct amination of unprotected 3-aryl and aliphatic substituted oxindoles with di-tert-butyl azodicarboxylate (DBAD) to construct a tetrasubstituted stereogenic carbon center at the C-3 position of oxindoles in good to excellent yield and enantioselectivity.
