(a)
Interpretation:
The given compound can be produced from two different Diels-Alder reactions. The reactants that would be required for each reaction are to be drawn.
Concept introduction:
The Diels-Alder reaction (also known as [4+2] cycloaddition) joins a conjugated diene and a dienophile (an
If the double bonds in the diene are either both trans or both cis, then the substituents at the ends of the diene become cis to each other with respect to the plane of the ring in the product. Electron-withdrawing groups must be a part of a dienophile while electron-donating groups must be a part of the diene to facilitate the cycloaddition. The stereochemical configuration in the dienophile is conserved throughout a Diels-Alder reaction.
(b)
Interpretation:
Out of the two sets of reactants, which set would be a better choice is to be identified and exaplained.
Concept introduction:
The Diels-Alder reaction (also known as [4+2] cycloaddition) joins a conjugated diene and a dienophile (an alkene or an alkyne) via the formation of two new sigma bonds. The six membered ring of carbon atoms has formed as a product.
If the double bonds in the diene are either both trans or both cis, then the substituents at the ends of the diene become cis to each other with respect to the plane of the ring in the product. Electron-withdrawing groups must be a part of a dienophile while electron-donating groups must be a part of the diene to facilitate the cycloaddition. The stereochemical configuration in the dienophile is conserved throughout a Diels-Alder reaction.
