A NOVEL PROCESS FOR THE SYNTHESIS OF SPIRO FUSED DIHYDROIMIDAZO QUINOLONE CARBOXAMIDES AND QUINOLINE

摘要

The invention relates to the novel process for the synthesis of new tricyclic quinolone carboxamide and quinoline derivatives fused at 7,8 positions by dihydroimidazole ring as in I and II. Novel molecules such as 7,8 fused spirodihydroimidazo fused quinolones I, II are prepared.
