Catalytic enantioselective synthesis of inherently chiral calix[4]arenes via organocatalyzed aromatic amination enabled desymmetrization

Nature Communications
Inherently chiral calix[4]arenes represent a distinct class of chiral frameworks whose chirality arises from the dissymmetry of the entire molecule. Although these chiral scaffolds have been widely applied in various research fields, their catalytic ...

DFT‐assisted rational design of salan ligands for highly enantioselective Zr–salan‐catalyzed hydroxylation of cyclic β‐keto esters

Smart Molecules, EarlyView.
Guided by DFT calculations, the design of novel C1‐symmetric salan ligands without the involvement of Suzuki coupling was achieved, and the preparation of α‐hydroxy‐β‐ketoesters in 99% yield and 99% ee was realized under low catalyst loading. Abstract In this work, a structurally simple, inexpensive, and readily accessible Zr–salan catalytic system was

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Influence of the Size of the Metallacycle of P‐NHC Mn Complexes for the Hydrogenation of Esters

Advanced Synthesis &Catalysis, Volume 368, Issue 18, 19 September 2026.
Does ring size matter? For manganese‐catalyzed ester hydrogenation, expanding the P‐NHC chelate ring from five to seven members unlocks superior activity at half the catalyst loading, shorter reaction times, and broader substrate scope, including the complete depolymerization of poly(ε‐caprolactone).

Synthesis and Application of a New Cyclic Phosphoric Acid in Enantioselective Three-Component Mannich Reactions

Molecules
A novel point-chiral six-membered cyclic phosphoric acid was synthesized starting from an enantiopure precursor via a concise three-step route. Its catalytic performance was evaluated in enantioselective three-component Mannich reactions. Under optimized
