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.

Is the following true or false? To catalyse a Diels-Alder reaction a common approach involves the use of a Lewis acid capable of lowering the LUMO of the dienophile.
What is the delocalization energy and π-bond formation energy of (i) the allyl radical, (ii) the cyclobutadiene cation?
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
In the beginning of this video https://www.youtube.com/watch?v=9Ng6Zv9oLzk, what reason is given on why the dienophile likes the diene?
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.
