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 ...

Highly Thermally Stable and Efficient Ru/MAFO Catalysts for Glucose Hydrogenolysis to 1,2‐Propylene Glycol

GCB Bioenergy, Volume 18, Issue 9, September 2026.
A low‐loading (1.5 wt%) Ru/MAFO spinel catalyst with strong metal–support interaction achieves 100% glucose conversion and 59.3% 1,2‐PG selectivity. Its exceptional thermal stability and resistance to Ru sintering enable stable recycling, offering a highly active and durable system for sustainable biorefinery applications.

Conditional Variational AutoEncoder to Predict Suitable Conditions for Hydrogenation Reactions

Molecules
Reaction conditions (RCs) are a crucial part of reaction definition, and their accurate prediction is an important component of chemical synthesis planning. The existence of multiple combinations of RCs capable of achieving the desired result complicates

Topliss‐Guided Optimization of Acetanilide‐Based Soluble Epoxide Hydrolase Inhibitors: Exploring the Pentafluorosulfanyl Group as a Potency‐Enhancing Motif

ChemMedChem, Volume 21, Issue 16, 27 August 2026.
Can an amide analog retain the high potency of the classic urea motif in soluble epoxide hydrolase inhibitors? Through a single unconventional switch, the introduction of the underexplored pentafluorosulfanyl group into an amide analog of TPPU, the authors restored high inhibitory potency.

Nuclearity-dependent design principles of ruthenium catalysts for selective hydroconversion of diverse polyolefins

Nature Communications
Polyolefin waste presents a major upcycling challenge because of its chemical inertness. Ruthenium catalysts are highly active for polyethylene hydrogenolysis, but often overproduce methane and linear alkanes and show limited substrate scope.

Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst

Chemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

Identification of Siderophores With Unexpected Antibacterial Properties From Actinoplanes teichomyceticus

ChemBioChem, Volume 27, Issue 15, 14 August 2026.
Here, we report isolation of acyl‐desferrioxamines from Actinoplanes teichomyceticus as a mixture of iron and aluminum complexes. The fraction containing these molecules exhibited antibacterial activity. We synthesized these molecules and found that they only exhibited antibacterial activity in the presence of aluminum.
