The given diene and dienophilethat are used in the synthesis of the productare to be determined. Concept introduction: The Diels–Alder reaction is the reaction between a conjugated diene and a compound containing double bond. i.e. a dienophile. In theDiels–Alder reaction, two sigma bonds are formed from the expansion of the pi bond of the diene and dienophile. In this reaction the reactants are a diene and a dienophile out of whichtwo sigma bonds and one pi bond formation takes place. The Diels–Alder reaction is stereospecific and the reaction is syn addition and the dienophile retains the configuration in the product. Cyclic diene in which double bonds are in cis conformation are usually highly reactive in the Diels–Alder reaction.
