摘要: 作者合成了6-氟-3-(取代)苯基-4-(1H)-喹啉酮的5-氯衍生物与7-氯衍生物,二者极性差异小,难于分离,以混合物形式存在.所合成的化合物均未见文献报道,本文通过1H NMR上的化学位移、积分面积以及偶合常数确证了混合物中两组份的结构.

Abstract: Isoflavonoids are recognized to possess broad biological activities, such as cardiovascular, estrogenicity and so on.3-Pheny l-4(1H)-quinolinone derivatives are isosteres of isoflavonoids and they have similar spatial structures.So perhaps they can exhibit similar activities.5- Chloro-6-fluro-3-phenyl-4-(1H)-quinolinone derivatives and 7-chloro-6-fluro-3-phenyl-4- (1H)-quinolinone derivatives were desig ned and synthesized at the same time.It's difficult to separate them due to their similar polarity.Only two isomeres (4a, 4b)were separated. 1, 2, 3 were mix tures due to their similar polarity of the two corresponding isomeres.The structures were confirmed by 1H NMR and the contents of the mixtures were determined by HPLC.
