                                A series of 3-diethoxyphosphorylquinolin-4-ones and 3-diethoxyphosphoryl-1,8-naphthyridin-4-ones containing various substituents at N-1 and C-7 was synthesized in a four-step reaction sequence starting from readily available ethyl 2-chlorobenzoates or ethyl 2-chloronicotinates and diethyl methylphosphonate. Selected quinolinone and naphthyridinone products were transformed into free mono and diacids. (C) 2011 Elsevier Ltd.
