11-membered ring. The Diels–Alder precursor 24 was prepared in a convergent fashion from the dienyl phosphonate 17, the aldehyde 16 and the pyrrolidinone 21, with phenylselenenylation and oxidative elimination being used to convert the pyrrolidinone 22 into the unstable pyrrolinone 24. The Diels–Alder reaction of the pyrrolinone 24 under high dilution conditions gave the required endo-adduct 25 in a yield
