9-(Trifluoromethyl)pyrido[1′,2′:1,2]imidazo[4,5-b]quinoxalines (9-CF3-PIQs) were obtained from the cyclization of 2-amino-3-chloro-6-(trifluoromethyl)quinoxaline (1a) with some substituted pyridines. 3-[2-(4-Pyridyl)ethenyl]-9-CF3-PIQ, one of thus obtained 9-CF3-PIQs, cyclized with another molecule of 1a to produce the dihydro bis-PIQ-ethene derivative.
从2-氨基-3-氯-6-的环化反应获得9-(三氟甲基)吡啶并[1',2':1,2,]咪唑并[4,5- b ]喹喔啉(9-CF 3 -PIQs)。 (三氟甲基)喹喔啉(1a)与一些取代的吡啶。这样获得的9-CF 3 -PIQ之一的3- [2-(4-吡啶基)乙烯基] -9-CF 3 -PIQ与另一分子1a环合以产生二氢双-PIQ-乙烯衍生物。
