Abstract

The ultraviolet and the infrared spectra (region between 1750-1600 cm-l) of proaporphine/homoproaporphine and promorphinane/homopromorphinane alkaloids with a keto group on the ring D, conjugated either with two (cyclohexadienone compounds) or with one (cyclohexenone compounds) double bond, are discussed. Furthermore, the effect of the enol ether in the α-, α,α’- or β-position to the keto group and that of the electron donating substituents of the ring A on the uv and the ir spectra have been studied.
