โœฆ Synopsis

Intramolecular [3+2]

-photocyctoadditions of alkenyl methyl 1,4-naphthalenedicarboxylates, which contain rather remote alkene moieties corresponding to isobutene or a-methylstyrene, proceeded largely depending on the chain lengths to give [3+2]-adducts having nine-to eleven-membered ring systems as well as the characteristic five-membered ring structures. Intramolecular quenching of the fluorescence of the diester moiety by the alkene moiety was observed in response to the occurrence of the [3+2]-photocycloadditions.
