Patent ID: 8129569

Claim:
Ketone according to the general formula (I) wherein i=1 or 2, R3, R4, R5, R6, and R7 are each mutually and independently hydrogen, a halogen atom, NO 2 , a linear or branched, substituted or unsubstituted alkoxy group having 1 to 15 carbon atoms, or a linear or branched, substituted or unsubstituted alkyl group having 1 to 15 carbon atoms, and R1 and R2 are each mutually and independently a secondary, tertiary, or quaternary carbon atom, and Q is at least one divalent substituted or unsubstituted group having 1 to 10 carbon atoms and bridging R1 and R2, wherein by cleavage of the Cα-Cβ bond, a ketone according to general formula (II) and a compound according to general formula (III) are formed, wherein i, R1, R2, R3, R4, R5, R6, R7, and Q have the meanings indicated above, wherein the compound of general formula (III) is a cyclic terpene or cyclic terpenoid having a semicyclic double bond, and wherein the cyclic terpene or cyclic terpenoid is chosen from β-phellandrene (p-mentha-1(7),2-diene), α-fenchene (7,7-dimethyl-2-methylenebicyclo[2.2.1]heptane), β-fenchene (2,2-dimethyl-5-methylenebicyclo-[2.2.1]heptane), camphene (2,2-dimethyl-3-methylenebicyclo[2.2.1]heptane), sabinene (4-methylene-1-(1-methylethyl)bicyclo-[3.1.0]hexane), pinocarveol, β-pinene (6,6-dimethyl-2-methylenebicyclo-[3.1.1]heptane), trichodiene (1,4-dimethyl-4-(1-methyl-2-methylenecyclopentyl)cyclohexene), β-humulene ((1E,5E)-1,4,4-trimethyl-8-methylenecycloundeca-1,5-diene), or γ-humulene ((1E,6E)-1,8,8-trimethyl-5-methylenecycloundeca-1,6-diene), or from enantiomers and/or diastereomers thereof.
