A process for the preparation of 1-(2,2,6-trimethylcyclohexyl)-hexan-3-ol of the formula A
having a content of at least 30 wt. % of the corresponding trans isomer, based on the total amount of 1-(2,2,6-trimethylcyclohexyl)-hexan-3-ol of the formula A, with the following step:
Catalytic hydrogenation of a compound of the formula D
in which the broken lines represent a single double bond which is located in one of the three positions drawn in, in the presence of a rhodium catalyst to give 1-(2,2,6-trimethylcyclohexyl)-hexan-3-ol of the formula A.
一种制备式为A的1-(2,2,6-三甲基环己基)-己-3-醇的过程,其含有至少30重量%的相应的顺式异构体,基于式A的总量,在以下步骤中进行:在铑催化剂的存在下,对式D的化合物进行催化氢化,其中断裂的线代表位于所绘制的三个位置之一的单个双键,以得到式A的1-(2,2,6-三甲基环己基)-己-3-醇。
