Chemical Syntheses of 3′ and 5′ Phosphorylated Oligonucleotides: An Overview

European Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.
This review provides an overview of the various chemical methods employed in the synthesis of oligonucleotides bearing a phosphate group at their 3′ or 5′ end. Notably, it presents modified phosphoramidites and supports developed for this purpose. Oligonucleotides (ON) with a phosphate monoester group at their 3′ or 5′ end have applications in many ...

Gold(I)‐Catalyzed C(sp3)–C(sp) Cross‐Coupling: Access to Alkynylated Tetrahydrofuran Derivatives

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
An Au(I)‐catalyzed C(sp3)–C(sp) cross‐coupling, unsuccessful under photosensitized conditions for vinylgold(I) complexes, is achieved using MeDalPhosAuCl under thermal conditions, giving alkynylated tetrahydrofuran derivatives. The reaction proceeds via an Au(III) intermediate formed by oxidative addition of an alkynyl iodide.

Rhodium(I)‐Catalyzed P(III)‐Directed C–H Alkylation of Biarylphosphines With Maleimides

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
A Rh(I)‐catalyzed P(III)‐directed ortho‐C–H bond alkylation of biarylphosphines with maleimides is disclosed. The reaction accommodates substituted alkenes, proceeds efficiently on gram scale, and consistently generates diastereomeric phosphines. NMR and mechanistic studies reveal that the stereochemical outcome arises from conformational restriction ...
