Abstract

NEW MATERIAL:An optically active or racemic tetralin derivative of formulaI (R is H or alkyl).
EXAMPLE: ( S )-3-( Carboxymethyl )-1,1,4,4,6-pentamethyl-1,2,3,4-tetrahydronaphthalene.
USE: Useful as an intermediate raw material for medicines, agricultural chemicals, perfumes, etc. For example, compounds obtained by the decarboxylation and acetylation are useful as perfumes, and among them 7-acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronaphthalene (trade name "Tonalid ") has a musky odor, and useful as a cosmetic perfume.
PROCESS: 4-(2-Methylpropenyl)-5,5-dimethyltetrahydro-2-furanone is reacted with an aromatic hydrocarbon in the presence of an acidic catalyst to give a novel compound of formula II, which is then treated with a Friedel-Crafts catalyst to afford the compound of formula I.
