alternatively it was esterified, reduced to the alcohol, chlorinated and cyclized into the 6-chloro-7H-indeno[2,1-c]quinoline 8. Further reaction of the chloroindenoquinoline derivatives with N-methylpiperazine afforded the piperazinyl derivatives 4a-c.
报告了实现标题化合物的两种合成途径。关键中间体,即3-羧基-4-苯基-2(1个H ^) -喹啉酮9,直接环化成相应的6-氯-7- ħ -茚并[2,1- c ^ ]喹啉-7-酮10或或者,将其酯化,还原为乙醇,氯化并环化成6-氯-7 H-茚并[2,1 - c ]喹啉8。氯茚并喹啉衍生物与N-甲基哌嗪的进一步反应得到哌嗪基衍生物4a-c。
