Intra‐ and Intermolecular Glycosylation of d‐Idopyranosyl and 6‐Deoxy‐d‐ido‐heptopyranosyl Donors: Toward the Repeating Unit of Campylobacter jejuni HS:4c Capsular Polysaccharide

European Journal of Organic Chemistry, Volume 29, Issue 4, January 26, 2026.
A comprehensive glycosylation study of diversely protected and activated d‐idopyranosyl and 6‐deoxy‐d‐ido‐heptopyranosyl donors using intra‐ and intermolecular coupling strategies is reported. Intramolecular aglycon delivery afforded 1,2‐cis‐β‐idopyranosides, while intermolecular glycosylation yielded chromatographically separable α‐ and β‐linked ...

Stereochemical Dissection of the Strobilurin PKS Reveals the Complex Biosynthetic Logic of Iterative EZE Triene Construction

Angewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
The strobilurin iterative PKS assembles a remarkable EZE triene by varying its stereoselectivity during synthesis. Stereoselective 2R‐methylation of the triketide intermediate by the C‐terminal C‐methyltransferase domain induces the KR and DH domains to invert their native stereoselectivities and produce a Z‐configured intermediate.

Defluoroalkylation of Trifluoromethane with Organolithium Reagents: Mechanism and Synthesis of Fluoroalkenes

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
We report a rare example of the transformation of HCF3 into a fluoroalkene functional group through defluoroalkylation. We rationalise product formation through DFT calculations, scale‐up the synthesis through continuous flow methods, and show that a fluoroalkene reagent derived from HCF3 is a competent nucleophile for the fluoroethenylation of a range
