Iridium‐Catalyzed Linear‐Selective sp3 C−H Alkylation of N‐Methylamides Using Alkenes Enabled by Diphosphite Ligands

Chemistry – A European Journal, Volume 32, Issue 21, 1 June 2026.
An iridium‐catalyzed linear‐selective sp3 C─H alkylation of N‐methylamides with alkenes is described. This method tolerates various N‐methylacetamide derivatives and has a broad alkene scope. Mechanistic studies were also conducted. Internal alkenes can also be used through in situ consecutive alkene isomerization.

Crystal structure of the plant GABA aminotransferase AtGABA‐T from Arabidopsis thaliana

Acta Crystallographica Section F, Volume 82, Issue 6, Page 208-215, June 2026.
The crystal structure of A. thaliana γ‐aminobutyric acid aminotransferase (GABA‐T) reveals that plant GABA‐T belongs to the class III aminotransferase family and employs a C‐terminal arginine residue for γ‐aminobutyric acid recognition, in contrast to the N‐terminal arginine used by class II enzymes.γ‐Aminobutyric acid aminotransferase (GABA‐T) is a ...
