Recent Advances in the Preparation, Structural Modulation, and Applications of Metal–Organic Framework (MOF) Membrane Materials in the Field of Separation

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Metal–organic framework (MOF) membranes are a novel class of composite membranes. They use crystalline porous MOF materials as separation layers or functional fillers. Because of their well‐ordered and tunable pore structures and highly controllable chemical environments, MOF membranes show broad application prospects in gas separation ...

Serine Octamer Substitution Reactions With α‐Hydroxy Acids

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale The amino acid serine forms chiral magic number clusters, which can be studied using mass spectrometry (MS). Serine octamer clusters are also known to incorporate one or two nonserine monomers with serine monomers to make up the octamer.

Unspecific Peroxygenase‐Based Chemo‐Enzymatic Synthesis of Amino Alcohols for Pharmaceutical Preparation

ChemBioChem, Volume 27, Issue 18, 28 September 2026.
The conversion of amines using nonspecific peroxygenases has always presented a challenge. The use of specific protecting groups, combined with the integration of enzymatic catalysis into conventional chemical methods, opens up new possibilities for the direct and enantioselective synthesis of valuable pharmaceuticals in an innovative, cost‐effective ...

Peptide‐Enabled Nanoplatforms for Malaria and Leishmaniasis: From Intracellular Targeting to Translational Diagnostic Perspectives

ChemMedChem, Volume 21, Issue 18, 28 September 2026.
Peptide‐enabled nanoplatforms offer multifunctional strategies for the treatment and diagnosis of malaria and leishmaniasis. Liposomal, polymeric, and metallic nanocarriers, together with cell‐penetrating peptides and parasite‐derived mimotopes, can improve targeted drug delivery, stability, bioavailability, and intracellular localization.

Organocatalytic Enantioselective Addition of Malonates to Cyclic Imines: A Short Total Synthesis of Tetraponerine T‐1

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.
A stereoselective functionalization method of cyclic imines under mild organocatalytic conditions was developed. Bifunctional cinchona alkaloid catalysts combined with carefully optimized reaction conditions to suppress background reactivity enabled highly enantio‐ and diastereoselective addition reactions of malonates to cyclic imines.

Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence

Chemistry – A European Journal, Volume 32, Issue 36, 24 September 2026.
Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.

Asymmetric Synthesis of Tertiary α‐Aryl Stereocentres in Tetrahydro‐4H‐pyran‐4‐ones Using Pd‐Catalyzed Decarboxylative Asymmetric Protonation

European Journal of Organic Chemistry, Volume 29, Issue 36, 24 September 2026.
The Pd‐catalyzed decarboxylative asymmetric protonation (DAP) has been developed for sterically hindered tetrahydro‐4H‐pyran‐4‐one derived α‐aryl‐β‐keto esters. A substrate scope of nine examples of DAP showed that substrates containing a di‐ortho methoxy substitution pattern on the aryl ring gave rise to the highest enantioselectivities of up to 85 ...
