28- The following molecules can be formed by either: Michael Reaction; Enamine Acylation; Acetoacetic Ester Synthesis; Michael Addition; Malonic Ester Synthesis; Robinson Annulation; Aldol Condensation; Claisen Condensation; Intramolecular Aldol Condensation; Dieckmann Condensation or a Combination of two of the above listed reaction. In each case write the proper of the reaction on the line and dissect the product into appropriate starting material. In some cases there might only be one starting material. You may use any one of the above...
