a)
Interpretation:
The diene and dienophile used as starting materials in preparing the compound shown in a Diels-Alder reaction are to be stated.
Concept introduction:
In Diels-Alder reaction, a dienophile reacts with a diene to yield a cyclic adduct. The reaction takes place through 1,4 addition of the dienophile into the diene through a cyclic transition state. These reactions occur rapidly with dienophiles having electron withdrawing substituent groups in conjugation with the double bond and if the diene adapts a s-cis conformation during the reaction.
To state:
The diene and dienophile used as starting materials in preparing the compound shown in a Diels-Alder reaction.
