Give a reasonable synthesis for
each of the following compounds from the indicated starting
materials. You may use any other organic or inorganic reagents you
wish unless otherwise indicated. The desired product for each
reaction you propose must be the one of the predominant products.
Give the reactants, conditions (where appropriate) and products of
each synthetic step. If equal mixtures are anticipated (i.e. ortho
/ para products) then indicate where separations are needed. NO

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...
