o-phenylenediamine (2a) in chloroform at room temperature afforded the new azidopyridones 3. However, its fusion with 2a,b at 100–110°C gave the interesting pyrido[2,3-b][1,5]diazepines 4a,b. Alternatively, compound 4a could also be obtained by heating azidopyridones 3 at 100–110°C. When compound 1 was allowed to react with hydrazines 7a-d at room temperature it gave the corresponding azido compounds 8a-d
在室温下,在氯仿中将6-叠氮吡啶酮衍生物1与邻苯二胺(2a)反应,得到新的叠氮吡啶酮3。然而,它在100–110°C与2a,b的融合产生了有趣的吡啶并[2,3- b ] [1,5]二氮杂4a,b。或者,也可以通过在100–110°C下加热叠氮吡啶酮3来获得化合物4a。当化合物1在室温下与肼7a-d反应时,得到相应的叠氮基化合物8a-d。1与苯肼的融合(7d)在140–160°C的温度下提供了新的氨基吡啶酮10。通过在室温下与过量的烷基胺反应,还可以将6-叠氮基吡啶酮1转化为相应的6-烷基氨基吡啶酮15a-d。
