Nouveaux corps odorants dans Ie domaine des muscs polycycliques

open access: yesCHIMIA, 1992
Polyalkyl-tetralins and -indans are well known as starting materials for polycyclic musks obtained by Friedel-Crafts acylation. If, instead, such hydrocarbons are subjected to benzylic (electrochemical) oxidation, new musks are obtained.
