A series of 14 3-substituted 4-oxoquinolones with or without a substituent (methyl, ethyl) in position 1 were prepared. Literature and measured data were used to study the inÑuence of the substituent on the shifts of carbon atoms of these compounds, which are model compounds for antibacterial drugs
