Ethoxymethylenemalonic ester syntheses

This closely related synthesis uses /3-ketoesters and leads to quinolones. Anilines and /9-ketoesters can react at lower temperatures to give the kinetic product, a / -aminoacrylate, cyclisation of which gives a 4-quinolone. At higher temperatures, / -ketoester anilides are formed and cyclisation of these affords 2-quinolones. / -Aminoacrylates, for cyclisation to 4-quinolones, are also available via the addition of anilines to acetylenic esters or by reaction with diethyl ethoxymethylenemalonate (Et0CH = C(C02Et)2 ArNHCH = C(C02Et)2). ... [Pg.133]
