Diels–Alder reaction of a monosubstituted diene (such as CH2=CH–CH=CHOCH3) with a monosubstituted dienophile (such as CH2=CHCHO)gives a mixture of products, but the 1,2-disubstituted product oftenpredominates. Draw the resonance hybrid for each reactant, and use thecharge distribution of the hybrids to explain why the 1,2-disubstitutedproduct is the major product.

Furan and maleimide undergo a Diels–Alder reaction at 25 °C to give the endo isomer of the product. When the reactiontakes place at 90 °C, however, the major product is the exo isomer. Further study shows that the endo isomer of theproduct isomerizes to the exo isomer at 90 °C.furan: O maleimide:OON H(a) Draw and label the endo and exo isomers of the Diels–Alder adduct of furan and maleimide.(b) Which isomer of the product would you usually expect from this reaction? Explain why this isomer is usually favored.(c) Examine your answer to (b) and determine whether this answer applies to a reaction that is kinetically controlled orone that is thermodynamically controlled, or both.(d) Explain why the endo isomer predominates when the reaction takes place at 25 °C and why the exo isomer predominates at 90 °C
Mechanism The Diels-Alder reaction is part of a class of reactions known as a cycloaddition reaction. This reaction is specifically a [4+2] cycloaddition which is a concerted (one-step) process in which two new carbon - carbon sigma bonds are formed from two pi bonds. For the first Diels - Alder step of the mechanism fill in the arrows needed for the transformation. The rest of the mechanism is drawn for you. OH Show mechanism arrows for this step! 4 + 2 cycloaddition OH H D- & H+ transfer OH Nuc acyl substitution H L.G.
