✦ Synopsis

From the hexane extracts of a Colombian specimen of Pseudopterogorgia elisabethae (Bayer) we have isolated elisapterosin D (2) and elisapterosin E (3), two structurally complex polycyclic diterpenes based on the rare elisapterane carbon skeleton. The structures of these scanty compounds were elucidated after interpretation of their combined spectroscopic data and NMR spectral comparisons with known elisapterane models.

A recent chemical investigation of the hexane extract of a Colombian specimen of Pseudopterogorgia elisabethae (Bayer) has led to the isolation of ileabethin (1). This novel diterpene possesses a previously undescribed carbon skeleton which appears to be biosynthetically related to the serrulatane (
