| titleOfInvention | Mixtures of tricyclo-decane-derivatives together with their preparation and use are perfuming- and flavoring materials |
| abstract | PCT No. PCT/EP84/00141 Sec. 371 Date Jan. 10, 1985 Sec. 102(e) Date Jan. 10, 1985 PCT Filed May 10, 1984 PCT Pub. No. WO84/04520 PCT Pub. Date Nov. 22, 1984.The invention concerns 1. Mixtures of tricyclo[5.2.1.02,6]decane derivatives, having principal isomers corresponding to the general formula A, wherein R1 and R2 are hydrogen atoms or are a methyl group or a hydrogen atom, one of the substituents being a methyl group and the other a hydrogen atom, R3 and R4 are hydrogen atoms or are a methyl group or a hydrogen atom, one of the substituents being a methyl group and the other a hydrogen atom, Y is a tetrahydrofurane system at C-4/C-5 or a substituted oxymethyl group at C-5 and a hydrogen atom at C-4, R5 is a hydrogen atom or a C1-C6-acyl-, C1-C6-alkyl-, C1-C6-alkenyl-, C1-C4-alkoxymethyl-, C1-C2alkoxycarbonyl-, formylmethyl-, or di-C1-C4-alkoxyethyl-group, and the broken lines indicate a C-C-single bond and a C-C-double bond or alternatively two C-C-single bonds. <IMAGE> R1, R2, R3, R4 = H R1, R2 = H, CH3 (1 x CH3) R3, R4 = H, CH3 (1 x CH3) <IMAGE> R5 = C1-C6acyl-, C1-C6alkyl-, C1-C6alkenyl-, C1-C4alkoxymethyl-, C1-C2alkoxycarbonyl, formylmethyl-, di-C1-C 4alkoxyethyl-group 2. Process for the preparation of these mixtures, wherein dimeric methylcyclopentadiene is selectively hydrogenated in the norbornane part and reacted with formaldehyde, paraformaldehyde or trioxane in the presence of a protonic acid or Lewis acid, optionally saponified or esters, ethers, acetates or oxoaldehydes prepared in known manner, and 3. the use of these mixtures as perfuming- and flavoring materials. |
