Herein, we describe the iron(III)-catalyzed oxidative coupling of alcohol/methyl arene with 2-amino phenyl ketone to synthesize 4-quinolone. Alcohols and methyl arenes are oxidized to the aldehyde in the presence of an iron catalyst and di-tert-butyl peroxide, followed by a tandem process, condensation with amine/Mannich-type cyclization/oxidation, to complete the 4-quinolone ring. This method tolerates

Polysubstitutedquinolines were efficiently prepared on the soluble polyethylene glycol (PEG) by microwave irradiation Friedländer condensation of PEG boundacetoacetate with 2‐aminoarylketones promoted by catalytic amount of polyphosphoric acid, and subsequently cleavage from the PEG with MeONa in MeOH. The polymer‐supported synthesis provided the target compounds in excellent yield and purity with
