Enantioselective cyanosilylation of aldehydes catalyzed by a multistereogenic salen–Mn(<scp>iii</scp>) complex with a rotatable benzylic group as a helping hand
A multistereogenic salen–Mn(iii) complex bearing an aromatic pocket and two benzylic groups as helping hands was found to be efficient in the catalysis of asymmetric cyanosilylation.
