Abstract
The crystal and mol. structure of graveolide (I), a sesquiterpene lactone from Inula graveolens, detd. by x-ray anal., confirmed that graveolide is a helenanolide, (C8 pseudoguaianolide), with transjunctions both at the lactone junctions and cyclpentane moieties. The seven-membered ring adopts a conformation intermediate between the C9 and TC6 types. The conformational features of graveolide are discussed and compared with those of the related helenanolides.
