Substrate‐Controlled Organocatalytic Divergent Annulations of γ, γ’‐Alkylidene Indane‐1,3‐Diones With Enals

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
A substrate‐dependent, regio‐ and stereocontrolled diversity‐oriented organocatalytic vinylogous Michael addition/cyclization cascade of γ, γ’‐alkylidene indane‐1,3‐diones with enals, using secondary amines as the catalyst, has been developed. A substrate‐dependent, regio‐ and stereo‐controlled diversity‐oriented organocatalytic vinylogous Michael ...

Conformational Landscapes in the Ground and Excited States Dictate Circularly Polarized Excimer Emission: A Thermodynamic–Kinetic Interplay in Carbazole Dimer Systems

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
Covalently linked carbazole dimers exhibit intense excimer‐based circularly polarized luminescence (CPL). A simple propylene‐tethered dimer achieves glum ≈ 0.01 in the violet region—among the highest for small organic emitters without heavy atoms. Conformational mapping reveals CPL is governed by thermodynamic/kinetic control of emissive conformers ...

Enantioselective Synthesis of Lactic Acid From CO2 Using a Novel Pyruvate Decarboxylase in a Scalable Biocatalytic Cascade

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
We report a scalable biocatalytic cascade that converts CO2 and acetaldehyde to pyruvate via a newly characterized pyruvate decarboxylase, followed by stereoselective reduction to lactic acid. The system enables fully switchable enantioselectivity using either L‐ or D‐lactate dehydrogenases.

Nanomaterial Integration at Liquid–Liquid Interfaces for Green Catalysis

Advanced Materials, Volume 38, Issue 34, 17 June 2026.
Functional nanomaterials assembled at liquid–liquid interfaces create dual‐role platforms serving as emulsion stabilizers and catalytic sites, offering enhanced reaction kinetics with improved catalyst recovery and recyclability. This review examines design strategies, structure‐performance relationships, and industrial implementation prospects of ...

Electrochemical Hofmann Rearrangement for Modular Synthesis of Unsymmetrical Ureas and Late‐Stage Modification of Drugs

Advanced Science, Volume 13, Issue 31, 4 June 2026.
An electrochemical Hofmann rearrangement of amide involving amine or other amide nucleophiles has been developed. The use of NaI guarantees the feasibility and compatibility of the electrosynthesis protocol, which enables highly chemoselective synthesis of unsymmetrical N‐acylureas from two different amides, as well as the production of unsymmetrical ...
