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.
Answer to Problem 16.51P
The diene and dienophile that are needed to prepare given product is shown below.
Explanation of Solution
The given product is shown below.
