A convenient one-pot synthesis of 1-alkyl-7-chloro-6-flouro-3-nitro-1,4-dihydro-4-quinolones is described via nitro-decarboxylation of the respective 4-oxo-1,4-dihydroquinoline-3-carboxylic acid precursors. Reduction of the former 3-nitroquinolones delivered the corresponding 3-aminoquinolones, envisaged as valuable synthons in drug research.
一种便捷的一锅合成法,通过相应的4-氧代-1,4-二氢喹啉-3-羧酸前体的硝基脱羧反应,制备1-烷基-7-氯-6-氟-3-硝基-1,4-二氢-4-喹啉酮。前述的3-硝基喹啉酮经过还原,得到对应的3-氨基喹啉酮,这些被视为药物研究中极具价值的合成砌块。
