C. Pericyclic Reactions and Orbital Symmetry (4 problems) 15. Predict the stereochemical outcome and mechanism (concerted step/TS drawing) for the thermal Diels–Alder reaction between cyclopentadiene and acrylonitrile; explain endo/exo selectivity. 16. Explain the product and allowedness for the electrocyclic ring-opening of 3,4-dimethylcyclobutene under thermal conditions; show orbital symmetry reasoning (Hückel/Möbius). 17. Propose a mechanism and predict products for a [3,3]-sigmatropic Claisen rearrangement of allyl phenyl ether; show stereochemical transfer. 18. Rationalize why the 6π electrocyclization of a conjugated triene proceeds thermally in a conrotatory or disrotatory manner (pick a specific triene and state outcome).

A tetracyclic compound with a congested tertiary C–H bond at the benzylic position adjacent to a piperidine ring.

By 3:30 AM, Lena was on a roll. She found a 2021 problem set from a professor in Cambridge (UK) that used visible light photocatalysis . The question showed an aryl diazonium salt and a simple furan.
