Abstract
On the basis of the results of an analysis of the optical rotatory dispersion curves and a consideration of possible conformations of labdane diterpenoids, the conclusion has been drawn that labd-8(17)-ene derivatives with a 13E double bond or a voluminous substituent in the side chain do not obey Garman's additive scheme, and when there are no asymmetric centers in the side chain they have more negative values of the molecular optical rotation than is preducted by this scheme.
