## Abstract Irradiation of the 2(1__H__)βpyrimidinones 1 in alcohols such as 2βpropanol and ethanol afforded the 1β(alkoxycarbonylamino)β3β(arylimino)β1βpropenes 4aβc, h and 2β(alkoxycarbonylamino)β4β(arylimino)β2βpentenes 4dβg. These photoproducts are formed by trapping the isocyanate intermediate
