Although the Dielsâ€“Alder reaction generally occurs between an electronrich diene and an electron-deficient dienophile, it is also possible to have inverse-demand Dielsâ€“Alder reactions between suitable electrondeficient conjugated double bonds and electron-rich alkenes. These reactions are particularly useful because they allow for the incorporation of heteroatoms into the new six-membered ring. Predict the products of each inverse-demand Dielsâ€“Alder reaction below. Be sure your products reflect the correct stereochemistry. If more than one regioisomer is possible, draw both.
Give major products for 1,2-/1,4-additions (A) Diels-Alder (B-D) cycloadditions [2+2] cycloadditions , and Retro-Diels-Alder (E) cycloaddition. Illustrate the regiochemistry and stereochemistry (me so, enatiomer., exo or Endo) for cycloadditions B-D?

Uemura and coworkers studied a time dependent Diels-Alder reaction which first formed the endo product as the major organic product and with time produced the exo product (J. Org. Chem. 2018, 83, 9300−9304). Show the endo and exo product for the reaction below. Which is the thermodynamic product and which is the kinetic product? Explain your reasoning.
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
