(a) Interpretation: The given compound can be produced from the two different Diels-alder reactions. The reactants that can be used for each Diels-alder reaction are to be drawn. Concept introduction: The Diels–Alder reaction joins a conjugated diene and a dienophile (either an alkene or an alkyne ) via the formation of two new σ bonds. The product is a six-membered ring of carbon atoms. Substituents on the product are either part of diene or of dienophiles, reactants of Diels-Alder reaction. The C=C bond in the product can be assigned to two different six-membered rings, so the product can be produced from the two different Diels-alder reactions. Standard Diels–Alder reactions are facilitated by electrondonating groups attached to the diene and electron-withdrawing groups attached to the dienophile. Substituents that are cis to each other about the C=C double bond of the dienophile end up cis to each other in the new ring that is produced.

Interpretation Introduction

(a)

Interpretation:

The given compound can be produced from the two different Diels-alder reactions. The reactants that can be used for each Diels-alder reaction are to be drawn.

Concept introduction:

The Diels–Alder reaction joins a conjugated diene and a dienophile (either an alkene or an alkyne) via the formation of two new σ bonds. The product is a six-membered ring of carbon atoms.

Substituents on the product are either part of diene or of dienophiles, reactants of Diels-Alder reaction. The C=C bond in the product can be assigned to two different six-membered rings, so the product can be produced from the two different Diels-alder reactions. Standard Diels–Alder reactions are facilitated by electrondonating groups attached to the diene and electron-withdrawing groups attached to the dienophile. Substituents that are cis to each other about the C=C double bond of the dienophile end up cis to each other in the new ring that is produced.
