✦ Synopsis

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 (biflorane) skeleton. The structure of 1 was elucidated after interpretation of its combined spectroscopic data.

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 elucida
