diastereoisomers of 6-(3,4-epoxy-4-methylcyclohexyl)-2-methylhepta-2,5-dien-4-one were synthesized in the [2+1] cycloaddition reaction of α-atlantone, isolated compound from Cedrus atlantica essential oil, with m-chloroperbenzoic acid in CH2Cl2. The chemoselectivity of this cycloaddition reaction has been both experimentally and theoretically studied within the molecular electron density theory. Parr functions
