The 5,6,7,8-tetrahydro-1,7-naphthyridine (7) pharmacophore has the potential to serve as a confor-mationally-locked analog of the pharmacologically active 2-(3-pyridyl)ethylamine (1) core structure. This paper describes the synthesis of 5,6,7,8-tetrahydro-1,7-naphthyridine (7) via a five-step sequence, which affords a significant improvement over previously reported syntheses.
5,6,7,8-四氢-1,7-萘啶(7)药效基团可能具有药理活性的2-(3-吡啶基)乙胺(1)核心结构的构象锁定类似物。本文通过五步序列描述了5,6,7,8-四氢-1,7-萘啶(7)的合成,与以前报道的合成方法相比,它具有显着的改进。
