Photochemical Reactions of 1-Aryl-2(1H)-pyrimidinones in Alcohol
Nishio, Takehiko
, p. 71 - 74 (2007/10/02)
Irradiation of the 2(1H)-pyrimidinones 1 in alcohols such as 2-propanol and ethanol afforded the 1-(alkoxycarbonylamino)-3-(arylimino)-1-propenes 4a-c,h and 2-(alkoxycarbonylamino)-4-(arylimino)-2-pentenes 4d-g.These photoproducts are formed by trapping the isocyanate intermediates 2, generated initially by the Norrish-type I cleavage of the ArN-CO bond of the 2(1H)-pyrimidinones, with the alcohol. Key Words: Pyrimidinones / Photochemistry / Carbamates / Isocyanate intermediates
