    摘要: Provided is citronellol, which has an elegant rosy fragrance and is extremely useful for fragrance impartation to aromatic articles. A mixture of an alkylamine and isoprene in a molar ratio of from 1:4 to 1:4.5 is subjected to telomerization at 80 to 100° C. for 2.5 to 3.5 hours in the presence of an alkyllithium catalyst and/or phenyllithium catalyst to obtain a nerylamine compound containing 2 to 10 wt % &agr;-nerylamine compound represented by general formula (4). From this nerylamine compound, citronellol containing 2 to 10 wt % optically active 3,7-dimethyl-7-octenol is produced through the reaction steps of asymmetric isomerization, hydrolysis, and hydrogenation.
