characteristics of this model are that the phenylgroup is nearly perpendicular to the ester CO, i.e., the PhCCO dihedral angle is near 90°, and that the methoxygroup is close to the carbonyl oxygen. These features may have wider applications for chiral control by α-chiral ester groups in other types of reactions. Our results should renew interest in the use of chiral 1-acyloxydienes.
