Abstract
New chiral Co-salen complexes with tert-butyl group in position 5 of the aromatic ring in the structure have been synthesized and they were applied as a chiral catalyst. A dimeric chiral salen having a transition metal salt such as AlCl3, displayed very high catalytic reactivity and enantioselectivity for the asymmetric ring opening of epoxides to synthesize optically pure α-aryloxy alcohols via phenolic kinetic resolution.
