-
Page/Page column 45; 46, (2018/09/02)
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).

The acid-catalysed ring opening of a number of substituted nopinones to give 4-(2-propyl)cyclohex-2-enones is described.In an application of this reaction use has been made of pinane chirality in the synthesis of R-o-mentha-2,4-diene (13) by fluorosulfonic acid-catalysed rupture of cis-verbanone (8) to (4S,5R)- and (4R,5R)-5-methyl-4(2-propyl)cyclohex-2-enone (9 and 10) followed by reduction-elimination.
