✦ Synopsis

New chiral Mn(III) salen epoxidation catalysts 1 and 2 (a catalyst loading in the range of 2.0-0.4 mol%) have been investigated for enantioselective epoxidation of chromene derivatives to chromene epoxides using pyridine N-oxide as a proximal ligand with excellent conversions and chiral induction.
