Textbook Question
Chapter 13, Problem 44P
When furan and maleimide undergo a Diels–Alder reaction at 25°C, the major product is the endo adduct G. When the reaction is carried out at 90°C, however, the major product is the exo isomer H. The endo adduct isomerizes to the exo adduct when it is heated to 90°C. Propose an explanation that will account for these results.

3. Using the carbon sources provided and any other necessary reagents needed, propose a viable
synthesis for the product shown. Your synthesis must include a Diels-Alder reaction. For each
step in your synthesis be sure to show the reagents/conditions necessary for that step and also draw
the major product expected for each step leading to the product. You will also need to use reactions
discussed in previous chapters as well.
