The title compounds were studied by 1H, 13C, and 15N NMR spectroscopy.Since inversion at nitrogen is rapid on the NMR time scale even at low temperatures, kinetic protonation was used to estimate invertomer ratios at ambient temperature.Invertomer preferences appear to be consistent with the operation of steric factors.
DEILS-ALDER ADDUCTS FROM N-SUBSTTITUED TAUTOMERIC 2(1H)-PYRIDONE-2-HYDROXYPYRIDINES; 5,6-BENZO-AZABARRELENONES AND 5,6-BENZO-AZABARRELENES

Diels-Alder reactions of several N-unsubstitued tautomeric 2(1H)-pyridone-2-hydroxypyridines with benzyne were examined and found to afford 5,6-azabarrelenones, wich were converted to hitherto unknown 5,6-benzo-azabarrelenes.
