having the 2,3,4,5-tetrahydro-1H-benzazepine skeleton, was synthesized by utilizing the intramolecular Mitsunobu reaction of the corresponding 2-(4-hydroxybutyl)aniline derivative. In the intramolecular Mitsunobu reaction, effect of the substituent group on nitrogen atom, influence of the functional group applying to synthesis of the other metabolites (3, 4 and 5) and utilization of synthesis of 2-substituent
5-羟基-2,3,4,5-四氢-1H-苯并氮杂衍生物 (2),它是莫扎伐坦 (1) 的典型代谢物,具有 2,3,4,5-四氢-1H-苯并氮杂平骨架,利用相应的2-(4-羟基丁基)苯胺衍生物的分子内光信反应合成。在分子内Mitsunobu反应中,研究了取代基对氮原子的影响,官能团对其他代谢物(3、4和5)合成的影响以及2-取代基苯并氮杂衍生物合成的利用。
