Photochemical reactions of 1,4,6-trisubstituted pyrimidin-2-ones have been examined.Irradiation of 1,4,6-trisubstituted pyrimidin-2-ones (1a-k) in benzene yielded the photochemical electrocyclization products, 3,4,6-trisubstituted 2-oxo-1,3-diazabicyclohex-5-enes (2a-k) in 14-85percent yield as the sole product, while 1,6-dimethyl-4-dimethylaminopyrimidin-2-one (11) was photochemically inactive.The photoisomers (2a-k) were stable at room temperature.
