(a) Interpretation: The complete mechanism of the given reaction is to be determined. Concept introduction: Diels–Alder reactions are stereospecific: the stereochemistry of the product is identified by the stereochemistry of the reactant. The Diels-Alder reaction is a significant and commonly used technique for making six-membered rings. The reactant as conjugated diene and a double or triple bond termed the dienophile . This is cycloaddition reaction therefore the dienophile has two and the diene has four pi-electrons that shift position in the reaction.
