Telluroesters: Synthesis and Reactivity in Nucleophilic Acyl Substitution

Advanced Synthesis &Catalysis, Volume 368, Issue 20, 16 October 2026.
A simple and general protocol to access telluroesters, a versatile class of organotellurium compounds serving as precursors of acyl radicals, is described. Their previously unexplored reactivity in nucleophilic acyl substitutions enables the efficient transfer of acyl moieties onto a broad range of nucleophiles under mild conditions.

A Library of Versatile Lignocellulose‐Derived Monomers From 5‐(Chloromethyl)furfural

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
5‐(Chloromethyl)furfural (CMF), an emerging bio‐based platform molecule, was coupled with lignin‐derived compounds to afford a library of ligno‐cellulosic monomers under mild and scalable conditions. The products were isolated in high yields without chromatographic purification and further reduced to renewable diols, providing versatile building blocks

Directional Second Sphere Effect on CO2 Activation and Reduction by Iron Porphyrin in Aprotic and Protic Media

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Directional control within the secondary coordination sphere redefines CO2 reduction by iron porphyrins. Simply rearranging identical urea hydrogen‐bond donors modulates reactivity, revealing that optimal catalysis does not only arise from maximal intermediate stabilization, but also from directional, adaptive non‐covalent interactions that balance ...

Oxidant‐Expedited Synthesis of H‐Phosphonates

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
An exceptionally mild method for synthesis of alkyl and aryl H‐phosphonates from phosphites is reported, requiring only water and O2 (including air) as reagents. Mechanistic experiments indicate that the role of O2 (and other oxidants) in the transformation is to promote a radical mechanism, and that H2O functions to provide both the hydrogen and the ...

Synthesis of Naphthoquinones by Pd‐Catalyzed Heck–Matsuda Arylation of Lapachol

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
Direct Heck–Matsuda arylation of lapachol enables the efficient synthesis of diverse naphthoquinones under homogeneous and heterogeneous palladium catalysis. The methodology features broad substrate scope, gram‐scale applicability, and provides a practical platform for quinone diversification.

Synthesis of S‐Linked Glycoconjugates of Monosaccharides and Levoglucosenone Derivatives Through Photoinduced Thiol–Ene Reaction Mediated by 4CzIPN and Its Water Soluble Analog

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
Visible‐light thiol–ene reaction mediated by 4CzIPN enables access to hydrolytically stable S‐linked glycoconjugates from levoglucosenone‐derived thiols (Y = 91% to quant. d.r. = up to >95:5) and conventional thio‐sugars (Y = 80% to quant. d.r. = up to >95:5).

A Modular Synthesis of C5‐Sulfenyl Thiazoles via an Intermolecular Pummerer Rearrangement: An Underexplored Scaffold for Medicinal Chemistry

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Modular access to underexplored C5‐sulfenyl thiazoles via an intermolecular Pummerer rearrangement is reported. The methodology exhibits a broad functional group tolerance enabling the seamless design of trisubstituted thiazole cores bearing a sulfur handle for further elaboration.
