On the basis of the newly proposed hypothesis on the olefin's approach to metal-oxo species, highly efficient (salen)manganese(III) complex (3) was synthesized as a catalyst for asymmetric epoxidation. With this catalyst, the highest level of enantioselectivity was realized in the epoxidation of conjugated cis-olefins.
