Short pathways are described for the synthesis of a representative example of each of the 7,8-dihydro-and 1,2,3,4-tetrahydro-1,6-naphthyridine-5(6H)-one ring systems from simple pyridine precursors. An attempted synthesis of the related 4,6-dihydro-1,6-naphthyridin-5(1H)-one ring system from a common intermediate was unsuccessful.
描述了由简单的吡啶合成7,8-二氢和1,2,3,4-四氢-1,6-萘吡啶-5(6 H)-一环系统中的每一个的代表性实例的短路径前体。从常见的中间体尝试合成相关的4,6-二氢-1,6-萘啶5(1 H)-环系统是不成功的。
