英文摘要: A new family of chiral ferrocenyl P,S-ligands has been developed and successfully applied in a highly endo-selective catalytic asymmetric cycloaddltion of azomethine ylides with various enones, including cyclic and acyclic alpha-enones. For cyclic alpha-enones, a [Cu(CH3CN)(4)]ClO4/(R-c,S-Fc)-2f complex catalyzed the cycloaddition to give the sole endo-cycloadducts in perfect enantioselectivities (normally 99% ee), while an AgOAc/(R-c,S-Fc)-2f catalytic system exhibited good endo/exo selectivities (endo/exo = 91/9 to 96/4) and high enantiocontrol (up to 98% ee) for acyclic alpha-enones.
