  Methods are provided for synthesizing the grape mealybug pheromone, trans-α-necrodyl isobutyrate, starting with essential plant oils that contain trans-α-necrodyl acetate. The synthesis method, in two steps, converts the trans-α-necrodyl acetate to trans-α-necrodol and then converts the trans-α-necrodol to the desired trans-α-necrodyl isobutyrate. The first step can be achieved by either of a hydrolysis reaction or a reduction reaction. In the hydrolysis reaction, the essential oil is mixed in an alcohol solvent with a hydroxide base, or by mixing the essential oil in an aqueous acid. A reduction reaction can instead by performed in an organic solvent in the presence of a reducing agent. The trans-α-necrodol is converted to the desired trans-α-necrodyl isobutyrate by an esterification reaction with a carboxylic acid, an acyl halide, or an acid anhydride.
