The invention relates to terpene-derived compounds, such as acids, esters thereof, produced by ozonolysis of terpenes, and to alcohols, amides, nitriles derived therefrom, as well as to processes for synthesizing them. Specifically, 2,3,7-trimethyloct-6-en-2-ol, 2,3,7-trimethyloct-7-en-2-ol, or a mixture thereof, produced by Grignard reaction of a terpene derived carboxylate with methyl magnesium bromide is disclosed.
