Use of defined cyclohexenones as agents for the superadditive enhancement of an olfactory impression and fragrance and/or flavor material composition

A compound of Formula (I) or of a mixture comprising two, three, four, five, six or a plurality of different compounds of Formula (I) for the superadditive enhancement of an olfactory impression. The invention also relates to novel fragrance and/or flavor material compositions which, in addition to a compound of Formula (I) or a mixture thereof, further contains one, two, three or a plurality of further fragrance and/or flavor materials, the fragrance and/or flavor material or the further fragrance and/or flavor materials not being compound of Formula (I).

Factors affecting product formation in the photolysis of α-spirocyclopropyl ketones

Photolysis of spirooct-7-en-4-ones results in exclusive β-cleavage in methanol to give 2-ethenylcyclohex-2-en-1-ones and in hydrocarbon solvents to give (E)- and (Z)-2-ethylidenecyclohex-3-en-1-ones.The solvent effect is ascribed to the role of metha

Nucleophilic and acid catalyzed cleavage of the cyclopropane rings of β,γ-unsaturated α-spirocycopropyl ketones

Treatment of isophorone (8) with sodium amide and 1,2-dibromomethane gives 6,6-dimethyl-8-methylenespirooctan-4-one (9) and 6,6,8-trimethylspirooct-7-en-4-one (10); similar treatment of 3-methylcyclohex-2-en-1-one (5) gives analogous spiro compo
