摘要

Copper-pyridineoxazoline (Cu-pyox) complexes are poor homogeneous catalysts for asymmetric cyclopropanation reactions. Pyox ligands have been immobilized by polymerization of monomers possessing a vinyl group directly attached to position 6 with styrene and divinylbenzene. The corresponding heterogeneous catalysts show a significant enhancement in enantioselectivity, up to 7-fold that of the analogous homogeneous Cu- ...
