the products react with amines, in the presence of copper(I) iodide, to form pyrrolo[3,2-c]cinnolines and with hydrazines to give either the same ring system or a pyrazolo[4,3-c]cinnoline. Hydrolysis of 3-alkynyl-4-phenoxycinnoline to 3-alkynyl-4(1H)-cinnoline, followed by cyclisation, yields the furo[3,2-c]cinnoline. Attempts to condense 3-halogenocinnolines with alkenes gave variable results: 3-phenyl
在Pd和Cu化合物作为催化剂的存在下,将3-溴-或3-碘-cinnoline(和4-取代的类似物)与末端炔烃缩合,得到3-炔基衍生物。当使用4-氯或4-苯氧基化合物时,在碘化铜(I)存在下,产物与胺反应生成吡咯并[3,2-c]辛啉,并与肼形成相同的环或吡唑并[4,3-c]肉桂啉。3-炔基-4-苯氧基肉桂酸水解为3-炔基-4(1H)-肉桂酸,然后环化,生成呋喃并[3,2-c]肉桂酸。尝试将3-卤代辛啉与烯烃缩合得到不同的结果:获得了3-苯基乙烯基-和3(2-吡啶基乙烯基)-4-(1H)-肉桂酮,但3-溴辛啉得到了3,3'-联萘啉。
