Abstract

Abstract Chiral Co III–salen complexes 1–6 bearing different substituents at the 3, 3′-and 5, 5′-positions of the salen unit, namely H, tBu, morpholinomethyl, and piperidinomethyl, have been synthesized. These complexes were used as catalysts in an environmentally benign protocol for the highly enantioselective aminolytic kinetic resolution (AKR) of racemic aryloxy/terminal epoxides with various carbamates as the nucleophile in the presence of ...
