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 ...

Pseudotetraivprolides from Pseudomonas entomophila Provide Insights into the Biosynthesis of Detoxin/Rimosamide‐Like Anti‐Antibiotics

Angewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
Pseudotetraivprolide is a new player among the Detoxin/Rimosamide‐like natural products! Its biosynthesis requires FabD from primary metabolism and a PipDFG complex for final‐step acetylation – unlocking its anti‐antibotic activity. Abstract Novel variants of known natural product (NP) classes can provide valuable insights into their biosynthesis ...

Enantioselective Syntheses of Secondary Alkylboronates via Asymmetric Regioselective Reduction of 1,3‐Dienylboronates

Angewandte Chemie, Volume 138, Issue 3, 16 January 2026.
We report herein the development of catalytic asymmetric synthesis of secondary alkyl boronates. Under the optimal conditions, Cu‐catalyzed semi‐reduction of 1‐alkyl‐ or 1,3‐dialkyl‐substituted 1‐boryl‐1,3‐butadienes forms secondary alkyl boronates with excellent regioselectivities and enantioselectivities.

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.
