3 pages, 2 figures, 1 table.-- PMID: 12444700 [PubMed].-- Printed version published Nov 22, 2002.Crystallographic data for the structure reported in this paper have been deposited with the Cambridge Crystallographic Data Centre (deposition number CCDC 185486).A new norditerpenoid, yaretol (1), was isolated from the whole plant of Azorella madreporica. The structure of 1 was established by one- and two-dimensional NMR techniques and confirmed by X-ray diffraction analysis.This work was funded by CONICYT/CSIC (Grant 2000-2-055), FONDECYT (Chile, Grant No. 1011068), and DICYT (Universidad de Antofagasta).
