STRUCTURAL ELUCIDATION OF MARINE HALOGENATED MONOTERPENES BY 2D-NMR AND NOE DIFFERENCE SPECTROSCOPY. A STEREOCHEMICAL CORRECTION

A new methodology for structural elucidation of polyhalogenated monoterpenes is presented. It makes extensive use of correlated 2D-NMR and NOEDS and shows that the structures of coccinene and its bromovinyl analog must be corrected to their C-2 epimers.
