Beyond the Solid Solution: Ordered Enantiomerically Unbalanced Packing in Surface‐Confined Tetrahelicene Monolayers

open access: yesChirality, Volume 38, Issue 5, May 2026.
Racemic dicyanotetrahelicene exhibits coverage‐dependent self‐assembly on Ag(111), transitioning from spontaneous chiral resolution at low coverage to a dense mixed phase at monolayer saturation. While submonolayer deposition produces extended homochiral domains, full coverage yields a compact, long‐range ordered lattice with an enantiomerically ...

Photoenzymatic Hydroalkylation Enables Streamlined Access to Aryl Glutarimide Precursors

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
We report a photoenzymatic hydroalkylation that enables streamlined, stereocontrolled access to aryl glutarimide precursors relevant to targeted protein degradation. Engineered flavin‐dependent “ene”‐reductases provide broad scope and high enantioselectivity through a distinct electron transfer–enantioselective proton transfer pathway.

Rhodium‐Catalyzed Regioselective Addition of N‐Hydroxyl Imides to Internal Alkynes

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 3, May 2026.
An intermolecular rhodium‐catalyzed regioselective addition of N‐hydroxyl imides to internal alkynes leads to branched O‐allyl compounds, which can be readily transformed to allylic alcohols and O‐allyl hydroxylamines after deprotection. Isotopic labelling experiments suggest a plausible reaction mechanism.

Isocitrate Dehydrogenase Mutations in Cancer: From Bench to Bedside Applications

open access: yesMedComm, Volume 7, Issue 5, May 2026.
Mutant isocitrate dehydrogenase affects multiple cancer types. Alterations in IDH1 and IDH2 result in abnormal enzyme activity, leading to the overproduction of D‐2‐hydroxyglutarate (D‐2HG). This metabolite disrupts cellular metabolism and epigenetic regulation, driving cancer initiation, progression, and metastasis.
