摘要

Abstract Synthesis of novel benzo [h]-1, 6-naphthyridines was successfully achieved by cyclocondensation of ethyl 4-aminoquinoline-3-carboxylates with malononitrile. The pyrazolo [4, 3-c] quinolines were synthesized by nucleophilic substitution and subsequent addition reaction of ethyl 4-chloroquinoline-3-carboxylates with different hydrazines. All new compounds were characterized by spectral and analytical methods. Graphical abstract
