3. The reaction of furan (1) and maleimide (2) gives two products, called exo and endo (and usually the endo product is the favoured product). i. Write the structures of these two products and label them appropriately. ii. Define briefly, with reference to the two structures drawn, exo and endo in the context of bridged bicyclic compounds. ii. What is the stereochemical relationship between these two products. NH 1 2

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. Carbon Sources Available H₂C=CH2 steps CH₂Br
