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).

Reactions of endocyclic linearly conjugated dienolates with Michael acceptors leading to bicyclo[2.2.2] octane derivatives. Application to the synthesis of C13 degradation products of carotenoids

The endocyclic linearly conjugated dienolates from substituted cyclohex-2-enones react with but-3-en-2-one, substituted methyl propenoates, but-3-yn-2-one and methyl propiolate to afford bicyclo[2.2.2]-oct-2-en-1-ols 10a-c, 14a-c and bicyclo[2.2.2]octa-2,5-dien-1-ols 15a,b. The AlCl3-catalysed reaction of 3,5,5-trimethyl-Htrimethylsiloxy)cyclohexa-l)3-diene 3 with (E)-4-acetoxy- and (E)-4-methoxy-but-3-en-2-one provides trans-8-acetoxy-7-acetyl-3,5,5-trimethyl-1-(trimethylsiloxy)bicyclo[2.2.2]oct-2- enes 22, 23 and trans-7-acetyl-8-methoxy-3,5,5-trimethyl-1-(trimethylsiloxy)bicyclo[2.2.2]oct-2- enes 24, 25. Starting from these bicyclo[2.2.2]octenes, the C13 degradation products of carotenoids including 3-oxo-α-ionone 20, blumenol-C 27 and 1,3,7,7-tetramethyl-2-oxabicyclo[4.4.0]decan-9-one 29 have been synthesized.

The fluorine atom as a cation-stabilizing auxiliary in biomimetic polyene cyclizations. 3. Use to effect regiospecific control

The fluorine atom substituted at the pro-C-13 position (steroid numbering) has been shown to be an effective cation-stabilizing (C-S) auxiliary in the acid-catalyzed cyclization of the polyene substrates 6, 7, and 8. The preparation of 6, 7, and 8 emploed
