Abstract
1 - 1-Dimethyl-octahydronaphthalene derivatives of formula <FORM:0896039/IV (b)/1> in which the broken lines indicate that a single double bond is present in one of the four positions shown are prepared by cyclising a compound of formula <FORM:0896039/IV (b)/2> wherein R2, R3 and R4 are hydrogen atoms o alkyl groups and R1 is a hydroxy, alkyl or alkoxy group or R1 is hydrogen and the compound is in the form of a Schiff's base, is cyclised with phosphoric acid or boron trifluoride, or mixtures thereof, at a temperature between -30 DEG C. and +75 DEG C. or with sulphuric acid and/or formic acid at a temperature between -30 DEG C. and +10 DEG C. The starting materials are obtained by a Diels-alder reaction between myrcene and an appropriate dienophile compound. The final products are odoriferous and may be used in perfumes. In examples: (1) myrcene and methyl acrylate are heated in the presence of phenyl-b -naphthylamine to give a starting material wherein R1=OCH3 and R2 to R4=H, which is cyclised with sulphuric acid, phosphoric acid or boron trifluoride to give 1 : 1-dimethyl-7-carbomethoxy - octahydronaphthalene and the starting materials and cyclised products wherein R1=CH3, R2=H, R3 and R4=CH3; R1=OCH3, R2=H, R3 and R4=CH3; R1=OCH3, R2=CH3, R3 and R4=H; R1=OH, R2=CH3, R3 and R4=H are similarly prepared: (2) the Schiff base (with aniline) of the starting material wherein R1 to R4=H is dissolved in benzene and heated with phosphoric acid to give 1 : 1-dimethyl-7-formyl-octahydronaphthalene.
