Syntheses of chiral C 2 -symmetric bidentate ligands having different ring sizes of cyclic amines and their catalytic abilities on enantioselective cyclopropanation of styrene catalysed by copper(I) triflate †
A series of chiral bidentate ligands having different ring sizes of cyclic amines have been synthesized. Their catalytic abilities on chiral inductions have been examined in the asymmetric cyclopropanation of styrene catalysed by copper(I) triflate.
