Electron-Poor Benzonitriles as Labile, Stabilizing Ligands in Asymmetric Catalysis
摘要:
[GRAPHICS]A chiral palladium catalyst [(S)-MeObiphep)Pd(NCAr)(2)(SbF6)(2), (S)-4c], has been developed for a variety of asymmetric transformations. (S)-4c is bench-stable and has activity comparable to that of the nitrile free Lewis acid catalyst for Diels-Alder, hetero-Diels-Alder, and glyoxylate-ene reactions.
