Synthesis of the Grape Mealybug Pheromone trans-alpha-Necrodyl Isobutyrate
Methods are provided for synthesizing the grape mealybug pheromone, trans--necrodyl isobutyrate, starting with essential plant oils that contain trans--necrodyl acetate. The synthesis method, in two steps, converts the trans--necrodyl acetate to trans--necrodol and then converts the trans--necrodol to the desired trans--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--necrodol is converted to the desired trans--necrodyl isobutyrate by an esterification reaction with a carboxylic acid, an acyl halide, or an acid anhydride.
