Next‐Generation Manufacturing: The Evolving Role of Biocatalysis in AstraZeneca

ChemBioChem, Volume 27, Issue 17, 14 September 2026.
Biocatalysis is strengthening AstraZeneca's manufacture of active pharmaceutical ingredients through faster development, robust scale‐up, and lower environmental impact. Case studies illustrate where biocatalysis delivers greatest value, while enabling platforms, teams, and partnerships shape its next phase.

Silylium‐Ion‐Initiated Disulfidation of Internal Alkynes With Disulfides

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
Silylium‐ion initiation enables the disulfidation of internal alkynes with diaryl disulfides. The catalytic turnover is maintained by the sulfonium ion ArS(ArSSAr)+ as a sulfenium‐ion carrier that reacts with an alkyne to form a thiirenium ion. Its ring opening by disulfide addition yields the 1,2‐bis(arylthio)‐substituted alkene product with E:Z > 95 ...

Strain-Release Pentafluorosulfanylation of Carbonyl-Containing Disubstituted Bicyclobutanes: A Fortuitous Path to SF₅-Containing Oxa[2.1.1]bicyclohexanes. [PDF]

Angew Chem Int Ed Engl
A regio‐ and diastereoselective method for strain‐release pentafluorosulfanylation of carbonyl‐containing 1,3‐disubstituted [1.1.0]bicyclobutanes (BCBs) was developed that led to several fortuitous discoveries. For instance, the resultant SF5‐cyclobutanes (SF5‐CBs) exhibit close SF5⋯C═X contacts (X = C, N, O) and provide synthetic access to a new class
