A novel four-component (five-molecular) diastereoselective synthesis of pyridinium salts 2-piperidinones is reported. The Knoevenagel–Michael–Mannich cascade reactions aromatic aldehydes (2 eq.), nitriles, ylides and ammonium acetate in ethanol provides convenient access to 1-((3RS,4SR,6RS)-5,5-dicyano-2-oxo-4,6-diarylpiperidin-3-yl)pyridin-1-ium halogenides with three stereocenters (55–85% yields) or...
