3- and 4-Pyridyliminopropadienones were prepared by flash vacuum thermolysis of Meldrum’s acid derivatives and characterized by low temperature IR spectroscopy. They react with dimethylamine to afford 1,5-, 1,6-, and 1,7-naphthyridones. The same naphthyridones are also obtained by microwave irradiation of the Meldrum’s acid derivatives. Quinolones were obtained by microwave irradiation of phenylam
通过对Meldrum的酸衍生物进行快速真空热解制备3-和4-吡啶基丙二酮,并通过低温红外光谱进行表征。它们与二甲胺反应,得到1,5-,1,6-和1,7-萘啶酮。通过麦德鲁姆酸衍生物的微波辐射也获得相同的萘啶酮。喹诺酮是通过微波辐射苯基氨基亚甲基-马德鲁姆酸和1-苯基吡咯-2,3-二酮获得的。
