title: Trinorsesquiterpenoids from the root extract of Pentalinon andrieuxii.
abstract: Two unusual trinorsesquiterpenoids, urechitols A (1) and B (2), were isolated from the root extract of Pentalinon andrieuxii, a plant used commonly in Yucatecan traditional medicine to treat leishmaniasis. The structures of 1 and 2 were identified by interpretation of their spectroscopic data and chemical correlation reactions. The relative stereochemistry of 1 was confirmed through an X-ray crystallographic study.
