The reagents used to prepare each of the given compounds via Diels-Alder reaction should be determined.

Concept introduction:

Cycloaddition reaction is a concerted addition reaction of two reactants to form a ring; in which two π-bonds are converted to two σ-bonds.

Diels-Alder reaction is a [4+2] cycloaddition reaction, in which a π-system having four atoms (diene) and a π-system having two atoms (dienophile) are undergoing in cycloaddition reaction and producing a substituted cyclohexene.

The configuration of dienophile will be retaining in the product.

Retro-Diels Alder reaction of a Diels-Alder product is an inverse process of Diels-Alder reaction. It will give the diene and dienophile used for the Diels-Alder reaction.

The mechanism of the Retro-Diels Alder reaction for the Diels-Alder product is drawn by using three arrows representing the shifting of one-π-bond and conversion of two σ-bonds to two π-bonds in the Diels-Alder product in a clockwise or counter clockwise fashion, so that the diene and dienophile will form.
