Synthesis of (E)‐β‐SF5‐Styrenes via a Heck Reaction of in situ Generated Vinylsulfur Pentafluoride†
Chinese Journal of Chemistry, Volume 44, Issue 11, Page 1823-1827, 1 June 2026.A Heck cross‐coupling reaction between aryl(hetero)iodides and in situ generated vinylsulfur pentafluoride is reported. This reaction provides β‐SF5‐styrenes in one‐step as a single (E)‐stereoisomer and tolerates a broad range of functional groups. Comprehensive Summary The synthesis of (E)‐(1‐alken‐1‐yl)pentafluoro‐λ6‐sulfanes, a valuable class of ...

Carbohydrate‐Based Drug Discovery: Synthetic Strategies and Clinical Applications
Israel Journal of Chemistry, Volume 66, Issue 3, May 2026.The picture depicts the molecules discussed in the review. On the left side, the general scaffold of sugars is shown. Next to it are four carbohydrate‐based molecules, including remdesivir, islatravir, empagliflozin, and Globo‐H. Remdesivir and islatravir contain a substituted ribose ring attached to a modified nucleobase.

Isocitrate Dehydrogenase Mutations in Cancer: From Bench to Bedside Applications
MedComm, 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.
