Write an equation for the Diels - Alder reaction of cyclopentadiene and 1.4-benzoquinone. Draw the structures for the "endo" and "exo" products from the reaction of cyclopentadiene with maleic anhydride. What are the products of the following Diels-Alder reactions? (Show the stereochemistry where applicable.) a) b) The Diel- Alder reacion is said to be "stereospecific." What does that mean in terms of product in each reaction in part a . In this experiment you will react cyclopentadiene (the diene) with maleic anhydride (the dienophile) to produce the bicyclic compound, endo-bicyclo[2.2.1]hept-5-ene-2.3-dicarboxylic anhydride. The endoadduct is formed exclusively. Why
