Flavoring with mono-oxomethyl substituted polyhydrodimethanonaphthalene derivatives

摘要

Described are mono-oxomethyl substituted polyhydrodimethanonaphthalene derivatives having the generic structure: <IMAGE> wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond; wherein R1, R1', R1'', R1''', R1'''', R3, R5, R5', R5'', R5''', R5'''' and R6 represent hydrogen or methyl with the provisos: (i) at least four of R1, R1', R1'', R1''' and R1'''' are hydrogen; and (ii) at least four of R5, R5', R5'', R5''' and R5'''' represent hydrogen; and wherein Z represents one of the moieties: (i) carboxaldehyde having the structure: <IMAGE> (ii) alkylene dioxy or dialkoxy methyl having the structure: <IMAGE> (iii) hydroxy methyl having the structure: <IMAGE> (iv) acetoxymethyl having the structure: <IMAGE> and wherein R7 and R8 taken separately represent C1-C4 lower alkyl or R7 and R8 taken together represent C2-C4 alkylene; wherein the line represented by: [++++] is either (i) a carbon-carbon single bond when R7 and R8 taken together are C2-C4 alkylene or (ii) no bond at all when R7 and R8 taken separately represent C1-C4 lower alkyl. Also described are processes for preparing such mono-oxomethyl substituted polyhydrodimethanonaphthalene derivatives, and processes for using the above defined mono-oxomethyl substituted polyhydrodimethanonaphthalene derivatives for their organoleptic properties and compositions containing said mono-oxomethyl substituted polyhydrodimethanonaphthalene derivatives including perfumes, perfumed articles (such as solid or liquid anionic, cationic, nonionic or zwitterionic detergents, perfumed polymers, fabric softeners and cosmetic powders), foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos, smoking tobaccos and smoking tobacco articles.
