Abstract
The new Mn-salen catalysts bearing (1R,2R,3R,6R)-3,6-dimethylcyclohexane-1,2-diamine as an ethylenediamine part was found to show higher asymmetric induction in the epoxidation of conjugated cis-olefins than the Mn-salen catalyst bearing optically active cyclohexanediamine as an ethylenediamine part. This result supports our proposal that olefins approach metal-oxo bond along nitrogen-manganese bond axis in salen-catalyzed epoxidation.This publication has 4 references indexed in Scilit:
