2. Design multi-step syntheses for TWO of the following targets. Show the reagents needed for each step and the product of each step. Special conditions: You must use cyclopentadiene as your starting material for all syntheses. You may use organic reagents containing 4 or fewer carbons, and any inorganic reagents. For any Diels-Alder reaction that you use (necessary for all targets!), the dienophile must be an a,ß-unsaturated carbonyl compound. Target 1: HO D Target 2: Doe Target 3: ro Target...
