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% α-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.摘要翻译： 提供的是香茅醇，拥有优雅的香味红润，是传授香味芳香的文章是非常有用的。 4至1：：在从1的摩尔比的烷基胺和异戊二烯的混合物4.5进行调聚反应在80至100℃进行2.5至3.5小时在烷基锂催化剂和/或苯基催化剂的存在下，得到 nerylamine化合物含有2至10重量％的由通式阿尔法-nerylamine化合物（4）
从这个nerylamine化合物，香茅醇含有2至10重量％的光学活性3,7-二甲基-7-辛烯醇是 通过不对称异构化，水解和氢化反应步骤进行制备。 -
