Abstract
Abstract New polycyclic Diels-Alder adducts which are formed on reaction of 8-vinyl-tricyclo-[5,2,1,0 2 ,6 ]-dec-8-ene or 8-hydroxy-8-vinyl-tricyclo-[5,2,1,0 2 ,6 ]-decane with alkenes or alkynes having one or two activating substituents, e.g., --COOH, --COOCH 3 , --COOC 2 H 5 , --CHO, --COCH 3 , --COC 2 H 5 or --CN. They have green, fresh, fruity and in some cases woody odors with long-lasting tenacity and/or fixing properties. They can be used as constituents of perfumes and of compositions for perfuming body care products, detergents and other consumer products.
