Synthesis of β‐Enamino Sulfoxides via Cine‐Substitution of 1‐Chlorovinyl p‐Tolyl Sulfoxides with Lithium Amides

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
The cine‐substitution of 2‐aryl‐1‐chlorovinyl p‐tolyl sulfoxides with lithium amides yields β‐enamino sulfoxides with high efficiency. β‐Enamino sulfoxides are desulfinylated via the sulfoxide/magnesium exchange reaction with isopropylmagnesium chloride to yield enamines.

A Revised Model for Muscarine Biosynthesis Involving Lysine Trimethylation

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
The fatal mushroom toxin l‐(+)‐muscarine is one of the most prominent natural products. We elucidated its biosynthetic origin in the sweating mushroom Collybia rivulosa based on incorporation of stable isotope‐labeled compounds and extensive mass spectrometric analyses.

Revisiting Hydrazine Moiety as a Scaffold for the Synthesis of Potential Antiviral Pyrazole Ribonucleoside Analogues

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
Three series of pyrazole ribonucleoside analogues were designed and synthesized. They were evaluated, along with some of their pronucleotides, for their antiviral activity against RNA viruses. Pyrazole ribonucleoside analogues were prepared via a linear approach starting with the reaction of D‐ribosylhydrazine with 1,3‐dicarbonyl or acrylonitrile ...

Benzo[cd]azulenyl: A Structural Isomer of Phenalenyl—Synthesis and Properties of Its Tri‐tert‐butyl‐substituted Derivative and Formation of a Thermal‐ and Photoresponsive σ‐Dimer

Chemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.
Benzo[cd]azulenyl, a nonalternant isomer of phenalenyl, is identified as a new member of the nonalternant hydrocarbon radical family. The tri‐tert‐butyl substituted derivative forms a stable σ‐dimer in the solid state. Upon exposure to external stimuli such as light and heat, the σ‐bond of the dimer dissociates, producing the monomeric radical.

N‐Glycosyl Triazoline Glycomimetics via Huisgen Cycloaddition With an Electron‐Deficient Alkene and BF3‐Catalysed Triazoline Fragmentation to Aziridines

European Journal of Organic Chemistry, Volume 29, Issue 22, 9 June 2026.
Glycomimetics with triazoline and aziridine groups were synthesised via diastereoselective Huisgen cycloaddition from glycosyl azides. Density functional theory was applied to define the mechanism for BF3 promoted aziridine formation. Triazoline and aziridine derivatives were synthesised by diastereo‐ and regioselective Huisgen cycloaddition of 2,3,4,6‐
