摘要: The structures of PF1092A (1), B (2) and C (3), new nonsteroidal progesterone receptor ligands produced by Penicillium oblatum, were elucidated spectroscopic analyses. These compounds possess an eremophilane-type sesquiterpene carbon skeleton differ only in that 1 2 are different monoacetates 3. absolute configurations 1-3 determined single crystal X-ray diffraction analysis the 4-bromobenzoyl ester measuring optical rotations acetylation products these compounds.
