drug molecules. Herein, we developed an efficient protocol to access aryl-dihydropyridazinone moleculesvia carbene-catalyzed asymmetric annulation between dinucleophilic arylidene hydrazones and bromoenals. Key steps in this reaction include polarity-inversion of aryl aldehyde-derived hydrazones followed by chemo-selective reaction with enal-derived α,β-unsaturated acyl azoliumintermediates. The
