Recent Applications of Propylene Carbonate as a Solvent in Sustainable Organic Synthesis
This review evaluates propylene carbonate (PC) as a non‐toxic green solvent in organic synthesis, highlighting its performance in key reactions including cross‐couplings, asymmetric hydrogenations, peptide synthesis and biocatalysis. Across these processes, PC delivers yields comparable to conventional and alternative green solvents.

Helical Folding of Abiotic Chiral Poly(phosphodiester)s
Design and structural analysis of a new class of phosphodiester foldamers are presented. These oligomers that fold into single helical architecture showed length and temperature stability dependence comparable to DNA duplexes. ABSTRACT Functions of biomolecules are intimately linked to their structures which result from the folding of a linear sequence

A new dual‐ligand rhodium catalytic system based on [RhCl(cod)]2, BINAP or BIPHEP, and a diphosphoramidite ligand enables the hydroformylation of olefins using paraformaldehyde as a syngas surrogate. The system efficiently converts vinyl arenes, alkyl olefins, cyclopentene, and allyl acetate with high activity and regioselectivity.

Escaping the Scaling Relationships in Oxygen Reduction Catalysis: Implications for PEM Fuel Cells
Escaping the scaling relationships of the oxygen reduction reaction is vital for hydrogen fuel cells. This outlook examines how interfacial heterogeneity, spanning the subsurface lattice, chemisorption layer, and near‐interface solvation volume, mechanistically decouples intermediate binding energetics.

Enantio-, atrop-, and diastereoselective macrolactonization to access type III cyclophanes
Although chiral substituents have been incorporated into ansa chains to stabilize the conformations of cyclophanes and modulate the biological activities of pharmaceuticals, the asymmetric syntheses of these atropisomers relies on substrate-induced ...

Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation
The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.

Metal‐Catalyzed Transformations of Carbon Dioxide Toward the Production of Commodity Chemicals
This perspective highlights how transition‐metal catalysis can enable the synthesis of economically attractive CO2‐derived commodity chemicals. By transforming waste CO2 into acrylic acid, cyclic carbonates, and other valuable products, these strategies provide a practical route for simultaneous CO2 sequestration and valorization, helping to align ...

Control of Multiple Stereogenic Elements in Diaryl Ethers
We report a chiral phosphoric acid (CPA)‐catalyzed desymmetrizing aminoacetalization strategy of proaxially chiral dialdehydes that enables the construction of diaryl ethers bearing both central and axial chirality.

A self‐assembled monolayer (≈0.9 nm) of an axially chiral binaphthol phosphoric acid derivative on a ferromagnetic Ni/NiOx substrate shows chiral‐induced spin selectivity (CISS) magnetoresistance of 50%–80%. This thermally and chemically robust functional stack shows the way towards practical spintronic devices based on the CISS effect.
