Popis: | Both enantiomers of oxindoles with adjacent tetrasubstituted cyclic and acyclic stereogenic centers can be obtained with excellent stereoselectivities by using either a cinchona alkaloid derivative (EDC) as catalyst or Takemoto′s catalyst in conjugate addition reactions of monothiomalonates (II) to isatin-derived N-Cbz ketimines. |
