A notably higher diastereoselectivity is observed in the dimethyldioxirane epoxidation of chiral allylic alcohols when less polar solvent mixtures are employed; this is interpreted in terms of a dipolar transition state with OH association through hydrogen bonding to the dioxirane, for which a preferential dihedral angle of >130 deg is estimated.
