Photocycloadditions of 4-Methoxy-2-pyridone to Olefins and Synthesis of 1,2-Dihydrocyclobutapyridin-3(4H)-ones

Article abstract of DOI:10.1039/c39800000537

Irradiation of 4-methoxy-2-pyridone (1) in acetone in the presence of electron-rich alkenes afforded the 3-azabicyclo<4.2.0>oct-4-en-2-ones (2a-c) as the major products, whereas photolyses in the presence of electron-deficient alkenes led to the 2-azabicyclo<4.2.0>oct-4-en-3-ones (4a,b) as the major products; base treatment of the former adducts gave rise to the novel 1,2-dihydrocyclobutapyridin-3(4H)-ones (3a-c).
