Abstract

A new one-pot preparation of 3,6-disubstituted pyridazines starting from β-nitro-β,γ-unsaturated ketones and hydrazine monohydrate is presented. The protocol entails two sequential steps, leading to the isolation of the title targets in satisfactory overall yields tolerating a good variety of additional functionalities.
