Cycloaddition to 1-[phthalazin-3-yl] -3-oxidopyridinium betaine, across the 2, 6-positions of the pyridine ring with 2 pi-electron addends, gave substituted 8-azabicyclo [3.2.1] oct-3-en-2-ones.
Structural and configurational assignments of the cycloadducts were deduced from PMR and IR spectral data
