Optical rotatory dispersion and circular dichroism data for some epicamphor derivatives

Abstract

O.r.d. and c.d. data are reported for the epimeric 2-phenyl and 2-hydroxy-2-phenyl derivatives of (–)-bornan-3-one. The observed contributions of the endo-phenyl and the exo-hydroxy-group to the amplitude or the Δε value are in an opposite sense to that predicted for alkyl groups by the Octant Rule, whereas the exo-phenyl and the endo-hydroxy-group give contributions as predicted by the Octant Rule.
