摘要:
Acid catalyzed cyclization of Diels-Alder adducts of myrcene of formula 3 is performed in the presence of hydroxyl-containing compounds, giving the resulting mixtures of isomeric acyloctahydronaphthalenes of formulas 1 and 2 enhanced quantities of isomers that are particularly useful in perfumery because of their woody-amber odors with, enhanced amber note. Formulas 1,2 and 3 are as follows: R 1 , R 2 , R 3 and the wavy lines have the meanings given herein.
