Abstract

Abstract We describe tandem combinations of Suzuki-aza-Wittig, Suzuki-condensation and aza-Wittigelectrocyclic ring closure reactions for the synthesis of new pyridazino [4, 5-c] isoquinolinone, pyridazino [4, 5-c] quinolinone and pyrimido [5, 4-c] quinoline derivatives. Keywords: Halopyridazin-3 (2H)-one, Suzuki reaction, aza-Wittig reaction, tandem reaction, iminophosphoranes
