- W2956121623 abstract "N-Methylisatoic anhydride reacts with the lithium enolates of esters to produce β-ketoesters 4 in nearly quantitative yield. Thermal cyclization of these relatively unstable intermediates afford the corresponding 3-substituted-4-hydroxy-1-methyl-2(1H)-quinolinones (5) in good yields. The reaction of the lithium enolate of 5-methyl-4-hexenoic acid ethyl ester (14) with various nuclear substituted isatoic anhydrides gives 4-hydroxyl-methyl-3-prenyl-2(1H)-quinolinones 8, 9, and 18 which are highly desirable intermediates in the synthesis of a variety of quinoline alkaloids. Treatment of 18 with DDQ furnishes oricine in 73% yield." @default.
