Control of Gemcitabine Activity With Blue and Red Light

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
Treating cancer with chemotherapy is generally associated with many side effects, which can be addressed by selectively releasing the desired drugs with visible light. Sixteen new blue light‐activatable cytostatics were introduced, with the gemcitabine derivative exhibiting ideal properties.

Conversion of Alcohols to Alkyl Chlorides Using the Bichloride Ionic Liquid [NEt3Me][Cl(HCl)n]

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
The ionic liquid [NEt3Me][Cl(HCl)1.61] is presented as a controllable source of HCl for the effective transformation of a broad range of alcohols into alkyl chlorides. The process eliminates the need for continuous handling of HCl gas and enables a recyclable IL‐based catalyst system. The solvent‐free chlorination of alcohols using the bichloride‐based

Flavin Catalysts in Organic Synthesis

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

The Expanding Role of Diazirines in Synthetic Methodology

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
Beyond their established role in photoaffinity labeling, diazirines have emerged as versatile reagents in synthetic chemistry. This review highlights their dual reactivity as carbene and nitrogen‐transfer precursors, showcasing mechanistic insights and diverse applications in cyclopropanations, cycloadditions, skeletal editing, amination, heterocycle ...

Synthesis of β‐ and γ‐Carbolinones Through a Fe(III)‐Mediated Radical 6‐Endo‐Trig Cyclization of Indole‐Based Ugi 4‐CR Adducts

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
A practical strategy for synthesizing β‐ and γ‐carbolinones from indole‐based Ugi 4‐CR adducts through an intramolecular radical cyclization using Fe(III)–H species is presented. This approach enables the efficient synthesis of spiro‐carbolinones under mild reaction conditions and demonstrates the effectiveness of secondary radicals in both cyclization
