process for the production of 3 - methyl - 2 - butensu00e4ure 2 isopropenyl - 5 - methyl - 4 - 1 - ylester witch

摘要

Disclosed is a method for commercially advantageously producing 2-isopropenyl-5-methyl-4-hexen-1-yl 3-methyl-2-butenoate with high yield. Specifically disclosed is a method for producing 2-isopropenyl-5-methyl-4-hexen-1-yl 3-methyl-2-butenoate represented by the formula (IV) below which is characterized in that a sulfonate compound represented by the general formula (III) below is obtained by reacting 2-isopropenyl-5-methyl-4-hexen-1-ol with an organic sulfonyl halide in the presence of a basic substance, and then the thus-obtained sulfonate compound is reacted with a senecioic acid in the presence of a basic substance. (In the formula, R represents a hydrocarbon group.)
