The first synthesis of novel fused pyridazines has been realized starting from 1,3-diketones involving a Diaza–Wittig reaction as a key step. A convenient strategy was elaborated to access versatile pyridazinederivatives allowing the variation of substituents at position 6 of the heterocyclic ring. In a first part, pyridazines bearing an ester group were synthesized as a model to evaluate the methodology
