Concept explainers
(a)
Interpretation:
The dienes and dienophile that would react to give the Diels-Alder product is to be predicted.
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 derivative. The dienophile adds to one side of the diene, and the diene adds to the one side of the dienophile. Thus, they have syn stereochemistry.
