Imine Reductase‐Mediated Regio‐ and Stereoselective Reductive Amination of Diamines

ChemCatChem, Volume 18, Issue 19, 14 October 2026.
Imine reductases (IREDs) have been employed as biocatalysts for the regioselective modification of diamines via reductive amination. The use of racemic diamines resulted in both regio‐ and enantio‐selective reductive amination via kinetic resolution. The application of this methodology has been demonstrated on a preparative scale by the synthesis of a ...

Stereoretentive Nucleophilic Aromatic Substitution Accesses Atropisomeric 4‐Amino‐N‐Arylquinolinium Salts

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
Quinolin‐4‐ones were converted to chloroquinolinium salts, allowing formation of axially chiral aminoquinolinium salts via an enantioretentive SNAr reaction with a variety of amine nucleophiles. The salts have a high rotational barrier, with a racemization half‐life of ∼1000s of years.

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.
