Abstract
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-dihydrocyclobuta[c]pyridin-3(4H)-ones (3a–c).Keywords
