Concept explainers
(a)
Interpretation: The diene and dienophile that are needed to prepare given product is to be stated.
Concept introduction: Diels-alder reaction is a cycloaddition reaction in which two molecules combine to form a new ring. In this type of reaction, syn addition takes place. It is a reaction between diene with a dienophile to yield a cyclohexene. The dienophile adds to one side of the diene, and diene adds to the one side of the dienophile. Thus, they have syn stereochemistry.
