The structure of enukokurin, a new jatrophane diterpenoid from the latex of <i>Euphorbia lateriflora</i>

The structure of enukokurin [1], a novel jatrophane ester from the latex of Euphorbia lateriflora, has been assigned on the basis of its 1H and 13C nmr spectroscopic properties. The positions of its ester linkages were determined using 2D δC/δH long-range correlation experiments and its relative stereochemistry by nOe difference spectroscopy
