Transition Metal‐Catalyzed Functionalization of Nonallylic Alkenyl Alcohols via Chain‐Walking Strategies

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
This minireview outlines recent advances in chain‐walking reactions of nonallylic alkenyl alcohols catalyzed by various transition metals, including palladium, ruthenium, rhodium, iridium, and nickel. Furthermore, the corresponding reaction mechanisms are discussed.

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.

Spectroscopy and Conformer‐Selective Photoelectron Circular Dichroism of Chiral Molecules

Chemistry – An Asian Journal, Volume 21, Issue 9, 14 May 2026.
Photoelectron circular dichroism (PECD) is a forward–backward asymmetry in the angular distribution of the electrons emitted by a chiral molecule ionized by a circularly polarized light (CPL). Its sensitivity to conformation is studied by one‐photon or resonance‐enhanced two‐photon ionization, the latter being conformer‐selective.

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.

Beyond the Solid Solution: Ordered Enantiomerically Unbalanced Packing in Surface‐Confined Tetrahelicene Monolayers

Chirality, Volume 38, Issue 5, May 2026.
Racemic dicyanotetrahelicene exhibits coverage‐dependent self‐assembly on Ag(111), transitioning from spontaneous chiral resolution at low coverage to a dense mixed phase at monolayer saturation. While submonolayer deposition produces extended homochiral domains, full coverage yields a compact, long‐range ordered lattice with an enantiomerically ...
