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 ...

Reductive 1,2-Arylation of Isatins
Organic Letters, 2022 We report an intermolecular Ni-catalyzed reductive coupling of aryl iodides and isatins to form 3-hydroxyoxindoles. In contrast to common metal-mediated methods, sec-butanol is used as a mild stoichiometric reductant resulting in benign waste products.

European Journal of Organic Chemistry, Volume 29, Issue 26, 13 July 2026.Azuleno[1′,2′:4,5]pyrrolo[2,3‐b]quinoxaline with a mesityl group as a solubilizing group was synthesized. By synthesizing derivatives in which various functional groups were introduced into two electronically distinct sites, the pyrrole nitrogen atom and the azulene five‐membered ring, we were able to reveal that the photophysical and electrochemical ...
