Abstract
Official abstract text for this publication.
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 M 1 represents Li, MgZ 1 , ZnZ 1 , Cu, CuZ 1 , or CuLiZ 1 , wherein Z 1 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 X 1 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).
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for preparing a 5-isopropenyl-2-methyl-8-nonenyl halide compound of the following general formula (4): wherein X 1 represents a halogen atom, the process comprising steps of: subjecting a nucleophilic reagent, 2-isopropenyl-5-hexenyl compound, of the following general formula (5): wherein M 2 represents Li, MgZ 2 , ZnZ 2 , Cu, CuZ 2 , or CuLiZ 2 , wherein Z 2 represents a halogen atom or a 2-isopropenyl-5-hexenyl group, to a coupling reaction with a 1,3-dihalo-2-methylpropane compound of the following general formula (6): wherein X 1 represents, independently of each other, a halogen atom, to form 5-isopropenyl-2-methyl-8-nonenyl halide compound (4).
