Trans effect on cobalt porphyrin catalyzed asymmetric cyclopropanation

Abstract

A significant trans effect of potential coordinating additives was found in asymmetric cyclopropanation catalyzed by Co(II) complexes of D 2-symmetric chiral porphyrins [Co(1)]. Among different additives, substoichiometric amounts of DMAP resulted in substantial increases in both diastereoselectivity and enantioselectivity. A related solvent effect on the catalytic system was also observed.
