Abstract
We prepared several efficient chiral N-benzoylpyrroridine-carboxylic a cid ligands for dirhodium-catalyzed asymmetric dipolar cycloaddition a nd found that the electronic effect of the dirhodium(II) complexes inf luenced the catalytic activity, and the electron-poor catalysts were s hown to be efficient for the reaction. Enantioselectivities of up to 9 8% ee were attained.
