Chiral recognition of diastereomeric 6-cedrols by vibrational circular dichroism.

The use of vibrational circular dichroism spectroscopy for the chiral recognition of the two epimers of 6-cedrol, tricyclic sesquiterpenes, which contains oxygen as the heaviest atom, is shown. Bands in the 1500-850 cm(-1) region of the spectra were analyzed to calculate the anisotropy factors (g), which provided the regions of maximum circular dichroism effect for each epimer.
