Es wird ein Verfahren zur Herstellung von cis-Dihydronopol und dessen Estern beschrieben. Entsprechende Ester des (-)-Nopol werden stereoselektiv durch heterogene Hydrierung in Gegenwart eines Platin- oder Platinoxid-Katalysators oder eines Ruthenium/Kohle-Katalysators hydriert und die erhaltenen cis-Dihydronopylester gewünschtenfalls in den entsprechenden Alkohol überführt.

The present invention provides a novel carboxylic acid ester compound useful as a fragrance component or a material for a compound fragrance and a method for producing the same, and provides a fragrance composition including the carboxylic acid ester compound. The present invention also provides an acyl fluorides of a 2,4-dimethyl-bicyclo[2.2.2]octane compound and the esters thereof, useful as the raw materials (inclusive of the intermediates of organic synthesis), for example, for the medicines, agricultural chemicals, fragrances, functional resins, optical functional materials and electronic functional materials. The carboxylic acid ester compound of the present invention is a compound represented by the general formula (1).
(In the formula, one of R1 and R2 is a methyl group and the other of R1 and R2 is - COOR, and R is an alkyl group having 1 to 4 carbon atoms.)
