(a) Interpretation: The product of given Diels-Alder reaction is to be drawn and the stereochemistry at all the stereogenic centers is to be indicated. Concept introduction: A chemical reaction that involves [ 4 + 2 ] cycloaddition is called Diels-Alder reaction. The reactant molecules that give rise to the product are diene and dienophile. The rate of reaction is fast when the electronegative group is attached to dienophile. In the sigmatropic rearrangement, the migration of the sigma bond takes place.
