What is Stereochemistry of chapliatrin and its congeners from Liatris gracilis about?

Re-examination of Liatris gracilis afforded the known sesquiterpene lactones chapliatrin, isochapliatrin, acetlisochapliatrin, five new closely related 5,10-epoxygermacranolides and a new eudesmanolide. The stereochemistry of the 5,10-epoxygermacranolides has been settled by an X-ray analysis of isochapliatrin. tThese tests were carried out under the auspices of the Developmental Therapeutics Program, Division of Cancer Treatment of the National Cancer Institute. \*The dotted C-10,0 bond of formulas la-lc was based on a then common misinterpretation of what constitutes an aoriented and a B-orientated bond emanating from C-10 ofcertain germacranolides when a three-dimensional model is transformed into a two-dimensional figure. In fact, the correct representation in the plane of our structures for chapliatrin and its congeners should have heen the one shown Mow. 0
