Highly Versatile Hydrogenative Functionalizations of Phthalimides Catalyzed by an Ag‐Alumina Zeolite Nanocomposite: One‐Pot Synthesis of 3‐Substituted Isoindolinones

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Heterogeneous‐catalyzed selective and versatile hydrogenative functionalizations of phthalimides have been developed for the first time. By using a solid nanocomposite formed by [Ag/Al2O3] material in combination with [H‐BETA] zeolite as cocatalyst, a broad range of 3‐functionalized isoindolinones have been accesed in one‐pot from phthalimides, H2 and ...

Catalytic Enantioselective Synthesis of Conformationally Stable C(sp2)−C(sp3) Naphthocoumarin Atropisomers

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
The enantioselective synthesis of naphthocoumarin adducts via a tandem organocatalytic 1,4‐addition/decarboxylation delivers excellent control over a newly forged stereocenter and yields configurationally stable synclinal atropisomers. The process features broad substrate scope and scalability, and its structural and mechanistic foundations are ...

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.

Hydrotreatment of Nylon 66 and Amide Model Compounds Over Sulfided NiMo Catalysts

ChemCatChem, Volume 18, Issue 9, 14 May 2026.
Hydrotreatment of nylon‐66 and the model amide N,N‐dibutylhexanediamide over sulfided NiMo/Al2O3 reveals competing hydrodenitrogenation and hydrodeoxygenation pathways, without formation of heterocyclic products. Pathway selectivity is influenced by reaction conditions and differs between the model compound and the real nylon sample.

Quantifying Carboxylate Burial in Synthetic Hydrophobic Pockets in Water

ChemistryEurope, Volume 4, Issue 5, May 2026.
How “buried” is a buried ion? Double mutant cycles quantify the cost of placing a carboxylate within a deep aromatic calix[4]pyrrole pocket in water. The penalty is only +1.3 to +3.0 kcal·mol−1 because water penetrates through cracks and the portal, creating a wet, high‐dielectric microenvironment.
