An organocatalytic asymmetric alpha-sulfenylation of 2-substituted indolin-3-ones with N-(alkylthio or arylthio)-succinimides has been developed for the first time using Cinchona-derived squaramide as the catalyst. Various chiral 2,2-disubstituted indole-3-ones with S- and N-containing heteroquaternary carbon stereocenters were obtained with up to 98% yield and 99% ee.
