[Uses]

4-Hydroxy-1-methyl-2(1H)-quinolone was used as nucleophile in electrochemical oxidation of catechols and the reaction was studied by cyclic voltammetry and controlled-potential coulometry. It was used in ceric ammonium nitrate-mediated oxidative cycloaddition of 1,3-dicarbonyls to conjugated compounds to yield substituted dihydrofurans, dihydrofurocoumarins, dihydrofuroquinolinones and dihydrofurophenalenones. It was used in the synthesis of :
  • 3-(4-methoxybenzyl)-4-hydroxy-1-methylquinolinone
  • 3-(benzo[d][1,3]dioxol-5-ylmethyl)-4-hydroxy-1-methylquinolin-2(1H)-one
  • 3-(4-chlorobenzyl)-4-hydroxy-1-methylquinolin-2(1H)-one
  • 3,3′-bis(4-chlorobenzylidene)-1,10-methylquinolin-2,20-(1H)-one
