Which of the following compounds can arise directly from a Diels-Alder reaction? Circle any structures that can. Then, identify the appropriate diene(s) and dienophile(s) that would lead to the compound. Pay attention to E-/Z- stereochemistry in all of the reactants. For those that cannot undergo a Diels-Alder reaction, please explain why.
Please answer both parts to the questions completely. I will rate the answer afterwards. For a diels-alder reaction between anthracene and maleic anhydride, are the exo and endo forms of product 9,10-dihydroanthracene-9,10-ɑ,β-succinic acid anhydride different stereoisomers or are they the same molecule? Explain your answer by drawing the molecule. Would it be favorable to get a 1,4-adduct of anthracene and maleic anhydride? Why or why not? If the 1,4-adduct of anthracene and maleic anhydride had formed, would it have different exo and endo isomers? Yes or no and why?
