## Abstract Irradiation of the 2(1__H__)‐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 intermediate
