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 ...

Heterogeneous Organocatalytic Synthesis of Propargylic Esters Using a Polymer‐Supported N‐Heterocyclic Carbene

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
A vinyl addition polynorbornene (VA‐PNB)‐supported N‐Heterocyclic carbene precatalyst is successfully used in the metal‐free coupling of terminal alkynes, carbon dioxide, and chlorides toward propargylic esters. The conversion of carbon dioxide into high‐value chemical scaffolds is a central challenge in modern green chemistry. In this study, we report
