Optically active, oxygenated, alicyclic compounds and their use as perfuming ingredients

The compounds of the formula wherein R1 and R2 represent, independently from each other, a hydrogen atom or a methyl group and R3 represents a linear or branched, saturated or unsaturated, lower alkyl radical, in the form of an optically active isomer of the formula wherein the wavy line indicates one or other of the two possible orientations of the OH group, and mixtures of these isomers can be used to impart fragrances of the woody and amber-scented type, devoid of any animal/perspiration characteristics, to consumer products.

Rhodium catalysed decarbonylation of optically active campholenal analogues

Campholenal analogues (+)-1a-d were decarbonylated with a catalytic amount of Rh/Al2O3 with only slight racemization. Experiment with other catalysts showed that racemization increases with the ability of the metal to form a π-allyl
