A series of substituted 2-phenyl-4-quinolones 8–11 have been synthesized in good yields via flash vacuum thermolysis (FVT) of 1-aryl-4-cyano-5-phenylpyrrole-2,3-diones 7a–e and 1-aryl-4-methoxycarbonyl-5-phenylpyrrole-2,3-diones 7f–j. The pyrrolediones 7 were prepared from amines 3 and benzoylacetonitriles 5a–e or methyl 3-arylamino-3-phenylprop-2-enoates 5f–j.
一系列取代的2-苯基-4-喹啉酮8-11通过对1-芳基-4-氰基-5-苯基吡咯-2,3-二酮7a-e和1-芳基-4-甲氧基羧基-5-苯基吡咯-2,3-二酮7f-j进行闪蒸真空热解(FVT)合成,产率良好。这些吡咯二酮7是由胺3与苯甲酮腈5a-e或甲基3-芳基氨基-3-苯基丙-2-烯酸酯5f-j反应得到的。
