The cycloaddition was confirmed to occur in the vapor phase. When methanol was placed at the cold trap prior to the pyrolysis of 1, only 2 (and 3) was obtained, but no methanol adduct was obtained. The reaction of the ketene intermediate with methanol was proved to be faster than the intramolecular cycloaddition by the photolysis of 1 in a solvent containing methanol
