21.32 (E)-9-Oxo-2-decenoic acid (compound 2), a pheromone of the honeybee queen, has been shown to have anti- bacterial and anti-inflammatory properties. One laboratory synthesis of this pheromone involved the preparation of 1, followed by the conversion of 1 into 2 Using an acetoacetic ester synthesis, show how 1 can be converted into 2. Note that the COOH group is mildly acidic, so the investigators first treated 1 with a base (CH NH) to remove the acidic proton. Make sure to include this deprotonation step in your proposed synthesis. OH HO OH
