The CD spectra of phorbol and of some of its derivatives, such as its 12, 13, 20-triacetate 1, show at least four bands. Three of them (called I, III, and IV) correspond to the R-, K-, and (perhaps) second n π*-transition, respectively, of the enone

The absolute configurations of (+)-cantharic acid, a chiral derivative of the achiral insect defensive substance cantharidin (1), and of palasonin, a lower homologue of 1 occurring in the plant Butea frondosa, were shown to be represented by formulas

With the help of PMO theory a non-empirical sector rule has been derived for the n ~ 1t5* band CD (around 260 nm) of the pentadienolide chromophore of steroidal bufadienolides. The rule was verified by experiment using the preferred conformation for
