Desymmetrization of Pseudo‐para Diformyl[2.2]Paracyclophane via Brønsted Acid‐Catalyzed Reductive Amination

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A highly stereoselective desymmetrization of pseudo‐para diformyl[2.2]paracyclophanes is developed via chiral Brønsted acid‐catalyzed reductive amination. This protocol provides efficient access to enantiopure planar chiral paracyclophanes with broad substrate scope, excellent enantioselectivity, and versatile postsynthetic functionalization. Access to

Asymmetric Transformations of α,β‐Unsaturated Oxazolidinones Catalyzed by C2‐Symmetric Chiral Iron Triad Complexes

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
This review highlights the evolution of highly enantioselective oxazolidinone transformations enabled by C2‐symmetric ligands, with emphasis on chiral iron triad complexes as cost‐effective, environmentally benign alternatives to late‐transition‐metal catalysts.

Strategic Functionalization of Benzylic C(sp3)H Bonds: Unlocking the Potential for Enantioselective δ‐Lactonization

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Recent advancements in bio‐inspired Mn‐catalyzed directed oxidations of carboxylic acids have provided promising pathways for the synthesis of a wide variety of chiral γ‐lactones. In our current study, however, we have established a catalytic route using 0.25 mol% of electron‐rich Mn‐catalyst Mn(dMMbpbp) that redirects the lactonization reaction to the

Dearomatization with Axial‐to‐Central Chirality Conversion

European Journal of Organic Chemistry, Volume 29, Issue 17, 5 May 2026.
Atropisomers are exciting synthetic targets with unique properties, which find applications in many fields of chemistry. However, considering them as substrates is not very frequent, notably in the context of dearomatization reaction. We wish to discuss the different strategies for the dearomatization of aromatic atropisomers with axial‐to‐central ...

Direct Mechanoorganocatalysis via Surface Functionalization of Milling Reactors With Amine Functions

ChemistryEurope, Volume 4, Issue 5, May 2026.
Surface functionalization of milling jars in epoxy resin furnished reactive milling jars, able to perform direct mechanoorganocatalysis with high efficiency, recyclability, and simplified purification. This proof of concept was applied successfully to base‐catalyzed Knoevenagel condensation and multicomponent reactions.
