SARSCoV 3CLpro is known to be a promising target for development of therapeutic agents against the severe acute respiratory syndrome (SARS). A quinolinonecompound 1 was selected via virtual screening, and it was synthetized and tested for enzymatic inhibition in vitro. Compound 1 showed potent inhibitory activity (IC50=0.44 µmol/L) toward SARSCoV 3CLpro. Further work on a series of quinolinone derivatives

cyanide and 18-crown-6. A one pot procedure is presented in which the esters do not need to be isolated. Reduction of the aryl ketones 4 and 11 with zinc dust leads to the benzyl derivatives 5 and 12. Reaction of the aryl ketones 4 and 11 with hydroxylamine and subsequent heating of the crude product leads via thermal Beckmann rearrangement and dehydration to oxazoloquinolones 7 and 14. 2-Aroyloxypyrido[1
