Barbituric Acids as Nucleophiles in Enantioselective Mannich Reactions: Organocatalytic Access to Quaternary Aminopyrazolone–Barbiturate Adducts

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
An enantioselective Mannich reaction using barbituric acids as nucleophiles provides access to chiral heterocycles bearing quaternary stereocenters. The transformation is catalyzed by a bifunctional thiourea with high selectivity. An immobilized catalyst enables recycling and application under continuous‐flow conditions, offering an efficient and ...
