A chiral (salen) manganese (III) complex 1 bearing a sesquiterpene salicylaldehyde and (R,R)-1,2-cyclohexanediamine moieties has been prepared. This complex catalyses the epoxidation of unfunctionalized olefins with iodosylbenzene and molecular oxygen/pivalaldehyde as terminal oxidants. In all cases the chemical yield was high although the enantiomeric excess obtained were low.
