Bay region diol epoxides of benzo[c]phenanthrene: Force-field molecular structures

Abstract

The molecular structures of the diequatorial and diaxial conformers of the syn- and anti-benzo[c]phenanthrene 'fjord-region' diol epoxide diastereoisomers have been determined by the Allinger force-field program. Certain features of steric crowding in the 'fjord-region' of the molecule that contribute to relative conformer stability are discussed.
