ether derivatives at the benzylic position of unsubstituted, dichloro, trichloro, and monobromo derivatives of the aromatic C-ring of dehydroabietic acid and podocarpicacid were synthesized and evaluated as BK channel openers in an assay system of CHO-K1 cells expressing hBKα channels. Detailed SAR analysis showed that the oximation was particularly effective in the cases of dehydroabietic acid derivatives

The rotatory dispersion and circular dichroism spectra of several ketones conjugated with an aromatic ring (derived from diterpenoids and steroids) have been studied. These compounds show Cotton effect curves with peaks near 350mμ. Extremely weak UV absorption maxima in the 320- 350 mμ region can be detected for these ketones in iso-octane solution. This would indicate that the perturbing light wave
