Guerry, Philippe ; Neier, Reinhard

In: Chimia, 1987, vol. 41, no. 10, p. 341-342

5,6-Dihydro-4-pyridones (3a-3c) undergo photochemical [2 + 2]-cycloaddition with olefins activated by an electron withdrawing group. Alkyi substituted double bonds could only be brought to react in the intramolecular cases 3d and 3e. Plus
