A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...

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 ...
