Abstract
The isolation and
structural elucidation of five new cembrane
diterpenes from two Eremophila
species is reported. (1R,3S,4S,7E,11Z)-3,15-Epoxy-19-oxocembra-7,11-dien-18-oic
acid (3) and (1R,3S,4S,7Z,11Z)-3,15-epoxycembra-7,11-dien-18-oic acid (7) were
isolated from E. granitica,
and dimethyl(1R,3S,4S,7E,11Z)-3,15-epoxycembra-7,11-diene-18,19-dioate (16),
(1R,3S,4S,8R,11Z)-3,15-epoxycembr-11-ene-18,19-dioic acid (14) and its dimethyl
ester were isolated from E. abietina. Structural studies on the diol derived from (14)
were carried out by single-crystal X-ray diffraction analysis.
