5,6,7,8-Tetrahydroquinolines and 5,6,7,8-tetrahydronaphthyridines with appended trifluoromethyl groups are valuable chemotypes in medicinal chemistry due to the presence of a partially-saturated bicyclic ring and metabolically-stable CF3 group. 1H NMR studies were used to optimize the preparation of such compounds, using a three-step/one-pot procedure, to provide novel 2,6-disubstitued derivatives with a tertiary-substituent. Racemic 2,6-disubstituted tetrahydroquinolines were separated by chiral HPLC to provide single enantiomers.
由于存在部分饱和的二环骨架和代谢稳定的CF3基团,带有附加三氟甲基的5,6,7,8-四氢喹啉和5,6,7,8-四氢萘啶是一类在药物化学中具有重要价值的化学类型。通过1H核磁共振研究优化了这类化合物的制备,采用三步/一锅法,得到了具有三级取代基的新型2,6-二取代衍生物。通过手性HPLC分离了外消旋的2,6-二取代四氢喹啉,获得了单一的对映体。
