Described are norbornyl pyridine derivatives defined according to the generic structure: [Figure] wherein R5, R5′, R5″, R5′″and R5″″each represents hydrogen or methyl with the proviso that at least four of R5, R5′, R5″, R5′″and R5″″represent hydrogen; wherein the dashed line represents a carbon-carb
Described are norbornyl pyridine derivatives defined according to the generic structure: [Figure] wherein R5, R5′, R5″, R5′″and R5″″each represents hydrogen or methyl with the proviso that at least four of R5, R5′, R5″, R5′″and R5″″represent hydrogen; 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 feedstuffs, 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: [Figure] wherein one of R1 or R2 is hydrogen and the other of R1 or R2 is vinyl with a bicyclopentadiene derivative defined according to the structure: [Figure] wherein R3, R3′, R3″, R3′″and R3″″each represents hydrogen or methyl with the proviso that at least four of R3, R3′, R3″, R3′″and R3″″represent hydrogen and wherein R4, R4′, R4″, R4′″and R4″″each represents hydrogen or methyl with at least four of R4, R4′, R4″, R4′″and R41 ″representing hydrogen and then as desired hydrogenating the resulting product.
