Short and efficient syntheses of 7-fluoro-8-(4-methylpiperazin-1-yl)-1,2,3,5-tetrahydro-5-oxopyrrolo[1,2-a]-quinoline-4-carboxylic acid and 8-fluoro-9-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydro-6H-6-oxopyrido[1,2-a]-quinoline-5-carboxylic acid are described. Both basic heterocycles were synthesized in two steps by the condensation of a benzoylacetate with an imino ether followed by an intramolecular
短而有效的合成7-氟-8-(4-甲基哌嗪-1-基)-1,2,3,5-四氢-5-氧代吡咯并[1,2 - a ]-喹啉-4-羧酸和8描述了-氟-9-(4-甲基哌嗪-1-基)-1,2,3,4-四氢-6 H -6-氧吡咯并[1,2 - a ]-喹啉-5-羧酸。通过将苯甲酰乙酸酯与亚氨基醚缩合,然后进行分子内亲核取代环化反应,在两个步骤中合成了两个基本杂环。
