摘要
N,N-Dimethy1-2-methoxy-3-trifluoroacety1-4-quinolylamine underwent chemoselective aromatic nucleophilic N-N exchange reaction with hydrazines followed by cyclocondensation to afford the corresponding novel fluorine-containing 4-methoxy-1H-and 2H-pyrazolo[4,3-c]quinolines in good to high yields. Furthermore, the use of 1,2-ethylenediamine and 1,2-phenylenediamines gave the corresponding fluorine-containing 6-methoxy-1,4-diazepino[6,5-c]quinoline derivatives in good yields.
