Tetrahydropyran monoterpenes from plocamium cartilagineum and pantoneura plocamioides

3 pages, 1 table.-- PMID: 9868144 [PubMed].-- Printed version published Dec 28, 1998.Four new marine monoterpenes have been isolated from two species of marine red algae, Plocamium cartilagineum and Pantoneura plocamioides. The structures and relative stereochemistry of these compounds were determined on the basis of spectroscopic evidence and suggest a relationship between P. cartilagineum and P. plocamioides.This work was supported by the Comisión Interministerial de Ciencia y Tecnología (CITYT) (ANT98-1069) and Instituto Antártico Chileno (INACH) and Subdirección General de Cooperación Internacional.
