A practical synthesis of 7-chloro-3-iodo-1-methyl-1,6-naphthyridin-2(1H)-one is described that starts from 2-chloro-4-(methylamino)nicotinaldehyde. The dihalo compound then undergoes sequential, site-selective Suzuki–Miyaura cross-coupling reactions to afford highly functionalized 1,6-naphthyridones in good yields.
7-chloro-3-iodo-1-methyl-1,6-naphthyridin-2(1H)-one 的实际合成描述了从 2-chloro-4-(methylamino)nicotinaldehyde 开始。然后二卤化合物经历顺序的、位点选择性的 Suzuki-Miyaura 交叉偶联反应,以良好的收率提供高度官能化的 1,6-萘啶酮。
