Metal‐Free Decarboxylative Allylation of N‐Protected Amino Acids and Carboxylic Acids via Thioxanthone Photocatalysis

ChemCatChem, Volume 18, Issue 17, 14 September 2026.
A mild, metal‐free photochemical decarboxylative allylic alkylation protocol using inexpensive thioxanthone under blue LEDs couples diverse carboxylic and N‐protected amino acids with Morita–Baylis–Hillman derivatives, offering broad substrate scope and a mechanism supported by radical‐trapping experiments.

N‐Aryl Acridone Derivatives as Effective Catalysts for Energy Transfer Reactions

Chemistry – A European Journal, Volume 32, Issue 33, 1 September 2026.
Acridones derivatives have high triplet energy, are simple accessible, and could be used in challenging [2+2] ENT reactions. ABSTRACT Organic photocatalysts capable of promoting high‐energy triplet energy transfer (EnT) remain limited, particularly for demanding [2+2] photocycloaddition reactions.

Stereodivergent Synthesis of C5‐α‐Substituted Linezolid Derivatives From D‐Mannitol and Structure–Antibacterial Activity Evaluation

Chirality, Volume 38, Issue 9, September 2026.
A stereodivergent route from D‐mannitol enables access to enantiopure C5‐α‐substituted linezolid analogues with full configurational control. Biological evaluation reveals that α‐substitution abolishes antibacterial activity irrespective of stereochemistry, establishing a strict steric limitation at C5 and highlighting the dominant role of substituent ...

Stereoselective Construction of Benzo‐Fused Tetrahydropyrrole Thiazines From Saccharin

European Journal of Organic Chemistry, Volume 29, Issue 33, 1 September 2026.
Saccharin was used as a template to construct a series of 10a‐substituted, benzo‐fused, pyrrolo thiazinone dioxides. Thereafter, diastereo‐divergent 10‐keto reduction gave either diastereomeric alcohol in a process that did not rely on the substituent at 10a's identity.
