Abstract
An alcohol with a new tricyclic humulane skeleton, laurobtusol, was isolated from the Mediterranean Red Alga Laurencia obtusa. The structure was established mainly by 2 D NMR methods and the relative configuration was assigned by a quantiative computer simulation of the lanthanide induced shifts in the H-1 NMR spectrum and Molecular Mechanics calculation (MM2).File in questo prodotto:
