Answer to Problem 16.60P
The Diels-Alder product formed by the given reaction is,
Explanation of Solution
The given reaction is shown below.
Figure 3
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. They have syn stereochemistry. The stereochemistry of dienophile in endo isomer is same as that of bridging ring system, whereas in exo isomer, it is in opposite.
Thus, the Diels-Alder product formed by the given reaction including stereochemistry is shown in Figure 4.
