Abstract

Three 8,17-epoxybriaranes, including a known metabolite, excavatolide M (1), as well as two new compounds, briastecholides K (2) and L (3), have been isolated from octocoral Briareum stechei collected off the waters of Taiwan. In this study, the absolute configuration of 1 was determined by single-crystal X-ray diffraction analysis for the first time. Moreover, the structures and stereochemistry of briaranes 2 and 3 were established based on spectroscopic analysis and comparison with those of 1.
