Beschreibung
Zusammenfassung:	A process for process for preparing 6-isopropenyl-3-methyl-9-decenyl acetate of the following formula (3), wherein Ac represents an acetyl group, the process comprising steps of: preparing a nucleophilic reagent, 5-isopropenyl-2-methyl-8-nonenyl compound, of the following general formula (1): wherein M1 represents Li, MgZ1, ZnZ1, Cu, CuZ1, or CuLiZ1, wherein Z1 represents a halogen atom or a 5-isopropenyl-2-methyl-8-nonenyl group, from a 5-isopropenyl-2-methyl-8-nonenyl halide compound of the following general formula (4): wherein X1 represents a halogen atom; subjecting the nucleophilic reagent (1), 5-isopropenyl-2-methyl-8-nonenyl compound, to an addition reaction with at least one electrophilic reagent selected from the group consisting of formaldehyde, paraformaldehyde, and 1,3,5-trioxane, followed by a hydrolysis reaction to form 6-isopropenyl-3-methyl-9-decenol of the following formula (2); and acetylating 6-isopropenyl-3-methyl-9-decenol (2) to form 6-isopropenyl-3-methyl-9-decenyl acetate (3).
