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 ...

Radical Cascade Combining Cross‐Olefin Coupling with the Smiles‐Truce Rearrangement

Angewandte Chemie International Edition, Volume 65, Issue 23, 1 June 2026.
We present a cobalt‐catalysed radical cascade that efficiently merges two alkene starting materials to form multiple bonds in a single step. The process begins with a cobalt‐catalysed hydrogen‐atom transfer‐to a styrene double bond, followed by a Giese addition.

Ion‐Pairing and Counterion Effects in Contemporary Photochemistry

Angewandte Chemie Novit, Volume 2, Issue 2, June 2026.
Ion‐pairing and counterion effects have emerged as fundamental yet underexplored determinants of photochemical behavior. Far from inert, counterions, and Coulombic interactions modulate excited‐state dynamics, quenching efficiencies, emission, and catalytic pathways.

The Development and Characterization of a Panel of Amine Dehydrogenases (AmDHs) and Amino Acid Dehydrogenases (AADHs)

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
The CoE‐AmDH panel enables sustainable access to chiral amines using diverse amine (AmDH) and amino acid dehydrogenases (AADH). Utilizing formate (FDH) or glucose dehydrogenase (GDH) for cofactor regeneration, this study establishes a robust screening platform for mild reductive aminations.
