    摘要: There is provided a method for preparing homofarnesol (1), the method comprising the steps of:



    a) providing farnesyl chloride (2)
    b) reacting farnesyl chloride (2) to homofarnesate (3) by alkoxycarbonylation; and
    c) reacting homofarnesate (3) to homofarnesol (1),

    wherein the configuration of the double bonds in the compounds 1, 2 and 3 is preserved.
