Process for the preparation of alkyl substituted tetralins and indanes |
| abstract |
The invention provides a process for the preparation alkyl substituted tetralins and indans wherein a benzyl alcohol having formula I: <CHEM> wherein R1 - R4 represent hydrogen atoms or alkyl groups having 1-3 carbon atoms and R5 and R6 are alkyl groups having 1-3 carbon atoms, is reacted with an alkene having 4-7 carbon atoms under the influence of a Lewis acid catalyst. Preferred benzyl alcohols are those wherein R1, R3 and R4 are hydrogen atoms and R2 is a hydrogen atom or a methyl group. Preferred alkenes are 2,3-dimethylbut-1-ene, 3,3-dimethylbut-1-ene, and 2 methylbut-2-ene. Preferred Lewis acids are AlCl3, FeCl3 and TiCl4. The tetralins and indanes produced are useful as intermediates for the production of well known musk fragrances. |
