Imidoylketene−Oxoketenimine Interconversion. Rearrangement of a Carbomethoxyketenimine to a Methoxyimidoylketene and 2-Methoxy-4-quinolone

, 2016
FVP of triazole 13 produces the isolable ketenimine 11 together with indole 15. 11 undergoes reversible interconversion with imidoylketene 10 above 380 °C. The latter cyclizes to quinolone 12.

Could traces of fluoroquinolones in food induce ciprofloxacin resistance in Escherichia coli and Klebsiella pneumoniae? An in vivo study in Galleria mellonella with important implications for maximum residue limits in food

Microbiology Spectrum
We hypothesized that the residual concentrations of fluoroquinolones allowed in food (acceptable daily intake—ADIs) could select for ciprofloxacin resistance in our resident microbiota.

Synthesis of 4-Quinolone N-Oxides via Controlled Partial Hydrogenation of 2-Nitrobenzoyl Enamines [PDF]

An operationally simple procedure for the synthesis of 2-alkyl-4-quinolone N-oxides, relying on controlled platinum-catalyzed partial hydrogenation of 2-nitrobenzoyl enamines, has been demonstrated. The P.

Inhibiting quinolone biosynthesis of Burkholderia

, 2021
2-Alkylquinolones are important signalling molecules of Burkholderia species. We developed a substrate-based chemical probe against the central quinolone biosynthesis enzyme HmqD and applied it in competitive profiling experiments to discover the first ...
