Cyclohexenylalkanol compounds (A) are new. Cyclohexenylalkanol compounds (A) of formulae (Ia) or (Ib) are new. R 1>, R 2>H or CH 3. Independent claims are included for: (1) a mixture comprising (A); (2) a perfume mixture with sandal wood smell comprising (A) and further ingredients; (3) a perfume product comprising the mixture and a carrier or substrate and/or in direct contact with the mixture; (4) the preparations of (A) and (Ia); (5) 6-(2,2,3-trimethyl-cyclopent-3-enyl)-1-oxa-spiro[2.5]oct-5-ene compound (XIV); (6) a cyclohexenyl compound of formulae (IXa) or (IXb); (7) preparation of (IXa) and/or (IXb), comprising reacting 2-(2,2,3-trimethyl-cyclopent-3-enyl)-propenal compound (X) with 1,5,5-trimethyl-4-(1-methylene-allyl)-cyclopentene compound (XI) by olefin ring-reaction, reacting (XI) with methane compound of formula (CH 2=CH 2-C(R 1>)(=O)) by diels-alder reaction and isolating (IXa) and (IXb); (8) preparation of (XIV) comprising allocating or producing 4-(2,2,3-trimethyl-cyclopent-3-enyl)-cyclohex-3-enone compound (XIII), converting carbonyl function of (XIII) into epoxide function to obtain (XIV); and (9) procedure for producing, reinforcing or modifying a sandal wood smell in a mixture comprising allocating (A) or its mixture, allocating a composition of other ingredients, and mixing of the composition of other components of (A) or its mixture that are sufficient to produce a sandalwood smell in the resulting mixture, to reinforce the sandal wood smell in the composition of other components or to modify the sandal wood smell in the composition of other components.
