Ozonolysis of the 2-oxo-1,3-diazabicyclo[2.2.0]hex-5-enes (2) in dichloromethane gave the 1,3-diazetidin-2-ones (3) in good yields, while ozonolysis of (2) in methanol gave the 1,3-diazetidin-2-ones (3), the cyclic acetals (4), and the unstable semi-acetals (5), which were identified as the acetate derivative (6).
