  Synthesis of .alpha.-Pyridone-Based Azaheteroaromatics by Intramolecular Vinylketene Cyclizations onto the C:N Bond of Nitrogen Heteroaromatics

  摘要：

  Substituted quinolizin-4-ones and ring-fused alpha-pyridone derivatives have been synthesized by the construction of 2,3-disubstituted-4-(2-azaheteroaryl)-2-cyclobutenones followed by thermal rearrangment. 4-(2-Azaheteroaryl)-2-cyclobutenones have been prepared regioselectively by the addition of 2-lithioazaheteroaromatics to cyclobutenediones and by palladium catalyzed cross-coupling of 4-chloro-2-cyclobutenones with 2-tri-n-stannylazaheteroaromatics. The thermal transformation is proposed to occur by ring-opening of the cyclobutenone followed by intramolecular cyclization of the transient vinylketene onto the carbon-nitrogen double bond of the azaheteroaromatic. A variety of quinolizin-4-ones, imidazo [1,2-a]pyridin-5-ones, 1-oxopyrido[2,1-b]benzothiazoles, and thiazolo[3,2-a]pyridin-5-ones were prepared.
