Atroposelective Construction of Axially Chiral Tetraarylethenes Via NHC‐Catalyzed Desymmetrization

Advanced Science, Volume 13, Issue 41, 22 July 2026.
We report the first NHC‐catalyzed atroposelective synthesis of axially chiral TAEs via oxidative desymmetrization of prochiral TAE dialdehydes. This catalytic strategy operates under mild conditions and accommodates a broad range of phenolic and nitrogen nucleophiles, delivering diverse axially chiral TAEs in good yields and up to 99% ee.

Asymmetric α‐Alkylation With Activated and Unactivated Electrophiles by a Highly Productive and Recyclable Lewis Acid/Imidazolium Catalyst

Angewandte Chemie International Edition, Volume 65, Issue 27, 1 July 2026.
An air‐stable, easily prepared, bifunctional Cu(II)/imidazolium complex enables highly enantioselective α‐alkylation of 1,3‐dicarbonyls with outstanding productivity (TON up to 1740). Highlights include broad electrophile scope spanning π‐activated and nonactivated reagents, stereo‐retentive allylation, simple catalyst synthesis, and efficient catalyst

Engineering a C–N Lyase for Selective Hydroaminations With Sterically Demanding Amines

ChemCatChem, Volume 18, Issue 13, 14 July 2026.
An engineered variant of ethylenediamine‐N,N’‐disuccinic acid lyase (EDDS lyase) shows a 600‐fold increase in activity toward sterically demanding bulky amines and efficiently converts large non‐native amines that are entirely unreactive with the wild‐type enzyme.

Mining for Novel Tryptophanase A: Extremophilic Organisms Ardenticatena maritima and Haloarcula japonica as Alternatives to E. coli in the Synthesis of Tryptophan Analogues

ChemCatChem, Volume 18, Issue 14, 29 July 2026.
Novel extremophilic tryptophanases (TnaAs) are tested in the synthesis of L‐tryptophan analogues. This study compares a thermophilic and a halophilic TnaA with E. coli TnaA as benchmark, from both structural and catalytic perspectives, revealing enhanced stability, and a broader substrate scope for the new homologues.
