Flavoring with norbornyl pyridine derivatives

Abstract

Abstract Described are norbornyl pyridine derivatives defined according to the generic structure: ##STR1## wherein R 5 , R 5 ', R 5 ", R 5 '" each represents hydrogen or methyl with the proviso that at least four of R 5 , R 5 ', R 5 ", R 5 '" and R 5 "" represent hdyrogen; wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond and wherein the pyridinyl moiety is bonded to the norbornyl moiety at the 2' position of the norbornyl moiety and at either the 2 or the 4 position of the pyridinyl moiety as well as organoleptic uses thereof in augmenting or enhancing the aroma or taste of foodstuffs, chewing gums, toothpastes, chewing tobaccos, medicinal products, perfume compositions, colognes and perfumed articles including, but not limited to solid or liquid anionic, cationic, zwitterionic and nonionic detergents, cosmetic compositions, fabric softener compositions, fabric softener articles, hair preparations, and perfumed polymers. Also described are processes for preparing such compounds comprising reacting vinyl pyridines defined according to the structure: ##STR2## wherein one of R 1 and R 2 is hydrogen and the other of R 1 and R 2 is vinyl with a bicyclopentadiene derivative defined according to the structure: ##STR3## wherein R 3 , R 3 ', R 3 ", R 3 '" and R 3 "" each represents hydrogen or methyl with the proviso that at least four of R 3 , R 3 ', R 3 ", R 3 '" and R 3 "" represent hydrogen and wherein R 4 , R 4 ', R 4 ", R 4 '" and R 4 "" each represents hydrogen or methyl with at least four of R 4 , R 4 ', R 4 ", R 4'" and R 4 "" representing hydrogen and then as desired hydrogenating the resulting product.
