The product that is formed when given diene reacts with methyl acetylenecarboxylate, a strong dienophile. Interpretation: The product that is formed when given diene reacts with methyl acetylenecarboxylate, a strong dienophile is to be stated. Concept introduction: Diels-alder reaction is a cycloaddition reaction in which two molecules combine to form a new ring. In this type of reaction, syn addition takes place. It is a reaction between diene with a dienophile to yield a cyclohexene. The dienophile adds to one side of the diene, and the diene adds to the one side of the dienophile. Thus, they have syn stereochemistry. In Diels-Alder reaction, the diene behaves like an electron rich species, whereas the dienophile behaves like an electron poor species.
