Abstract
Dihydromyrcenol (3,7-dimethylocta-1-en-7-ol) and carboxylic acid esters thereof are prepared from dimethylcyclooctene reactant mixtures comprising 1,5-dimethylcyclooctene in admixture with 1,6-dimethylcyclooctene and/or 1,4-dimethylcyclooctene by (a) thermally isomerizing the dimethylcyclooctene reactant mixture to afford a mixed octadiene product comprising 2,6-dimethylocta-1,7-diene in admixture with 2,7-and/or 2,5-dimethylocta-1,7-diene, (b) reacting the mixed octadiene product with a carboxylic acid to selectively form the ester of 3,7-dimethyl-octa-1-en-7-ol and (c) optionally hydrolyzing the ester of 3,7-dimethyl-octa-1-en-7-ol under basic conditions to yield dihydromyrcenol.
