Explain why diene B does not react in a Diels-Alder reaction with the dienophile maleic anhydride; however, diene A engages in a fast and efficient Diels-Alder reaction.
From the Diels–Alder reaction shown below, draw its resulting product.
Illustrate the steps of the given reaction:
How is the rate of a Diels-Alder reaction affected when a dienophile contains an electron-donating substituent?
How is the rate of a Diels-Alder reaction affected when a diene contains an electron-withdrawing substituent?
Draw the final products of the given chemical reaction.
Show the products of the following reaction. Explain how the products are formed by drawing a mechanism.
