RÉSUMÉ

A novel Pd/Cu catalyzed domino reaction for the synthesis of functionalized pyrrolo[1,2-b]pyridazines from readily accessible (hetero)aryl propargyl alcohols and 1-amino-2-bromopyrroles was developed. This cascade process involves a Sonogashira cross-coupling reaction, an isomerization and an intramolecular condensation.
