Abstract
Abstract 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.
