Abstract
Acid catalyzed cyclization of Diels-Alder adducts of myrcene is performed in the presence of hydroxyl-containing compounds, giving the resulting mixtures of isomeric acyloctahydronaphthalenes enhanced quantities of isomers that are particularly useful in perfumery because of their woody-amber odors with enhanced amber note.
