NHC-containing chiral bidentate ligands: Synthesis and evaluation in enantioselective copper-catalyzed conjugate addition
摘要:
New chiral phosphine-, thiolate-, mesylate-, and tosylate-containing N -heterocyclic carbene ligands have been synthesized in fair to excellent yield. These bidentate ligands have been evaluated in enantioselective copper-catalyzed conjugate addition to both cyclic and acyclic enones and displayed good catalytic activities and poor to good enantiomeric excesses (up to 80%).
