Abstract
A process for the manufacture of 7-(C1-8-alkoxy)-3,7 – dimethyloctan – 1 – als comprises ethynylating a 6-(C1-8-alkoxy)-6-methylheptan-2-one, esterifying the thus formed 7-(C1-8-alkoxy) – 3,7 – dimethyloct – 1 – yn – 3 – ol, rearranging and hydrolysing the thus produced ester and catalytically reducing the resulting 7 – (C1-8-alkoxy) – 3,7 – dimethyloct – 2 – en – 1 – ol. The 7 – (C1-8-alkoxy) – 3,7 – dimethyloct – 2 – en-1-ols are also claimed per se. The ethynylation may be effected with an alkali metal acetylide in liquid ammonia, the esterification with acetic anhydride in the presence of phosphoric acid and the rearrangement and hydrolysis with acetic acid in the presence of silver nitrate. The final products are used in perfumes (see Division A5).ALSO:Perfume compositions comprise a perfume or scent base and a 7-(C1-8-alkoxy)-3, 7-dimethyloctan-1-al (alkoxycitronellal). Other odour-imparting substances may be present.
