The estrogenic activity of a series of analogues of the daucane ester ferutinin (1a) modified at the acyl moiety was investigated in a yeast screen containing the human estrogen receptor a. Rather strict structure-activity relationships were observed. Thus, while the parent polvol (jaeschkeanadiol, 2a) was inactive, the presence of a p-hydroxybenzoyl moiety was necessary for activity in the yeast screen. Homologation and vinylation were both detrimental for activity, as were methylation of the p-hydroxyl substituent and the introduction of oxygen functions on the adjacent carbons.
