Catalytic asymmetric sulfenylation of 3-substituted oxindoles has been developed through efficient catalysis by tartaric acid derived chiral iminophosphoranes. With N-(phenylthio)phthalimide as the sulfur source, a wide range of optically active 3-phenylt

Sulfenylated oxindoles: The first asymmetric sulfenylation of N-Boc-protected oxindoles has been developed to provide products containing a tetrasubstituted stereogenic center in high to excellent yields (86-98 %) and, in most cases, excellent enantioselectivities (up to 96 % ee; see scheme).
