Oxaziridines: Versatile Reagents in Modern Organic Synthesis

open access: yesThe 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.

Titanium‐Catalyzed Diastereoselective Keto‐ and Iminonitrile Cyclizations

open access: yesChemistry – A European Journal, Volume 32, Issue 35, 19 September 2026.
The titanium(III)‐catalyzed diastereoselective cyclization of readily‐available substituted ketonitriles gives cyclopentanones in good yield and stereoselectivity. Subsequent 1,2‐addition allows the preparation of cyclopentyls with three consecutive stereocenters.

Unified Synthesis of Unconventional α‐Polyhalogenated Amines Through Hydroaminoalkylation

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 38, 14 September 2026.
A unified, redox‐neutral method that transforms alkenes and alkynes into α‐polyhalomethyl amines using stable hemiaminal reagents is reported. This approach enables access to CF3, CF2H, CF2Cl, and CFClH motifs, expanding halogenated amine space with broad substrate scope, functional group tolerance, and applicability to late‐stage modification of drug ...

Toward the Synthesis of Pestalustaine A: Structural Revision and Formation of Original Strained Tricyclic Architectures

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
Our synthetic endeavor toward the total synthesis of the reported unprecedented tricyclic skeleton of the sesquiterpene pestalustaine A allowed us to perform divergent cyclizations of a bicyclo[4.4.1]undec‐3‐ene into complex tricyclic architectures and to revise the structure of the natural product.

Photochemical Ring Opening of Cyclopropyl Silyl Ethers Enables β–β Coupling, Radical‐Polar Crossover and Annulation

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
A photochemical platform enables β–β coupling of cyclopropyl silyl ethers with electron‐deficient alkenes. The resulting adducts serve as entry points into annulative and radical–polar crossover pathways, providing rapid access to fused, bridged, and spirocyclic architectures, including late‐stage scaffold diversification to diterpene‐like carbocyclic ...

Synthesis and Evaluation of Peptoid‐Based Compound Libraries as Inhibitors of Parasite Metallo‐Aminopeptidases

open access: yesChemMedChem, Volume 21, Issue 17, 14 September 2026.
Evaluation of two libraries of peptoid‐based compounds for inhibitory activity against PfA‐M1 from Plasmodium falciparum, TcLAP from Trypanosoma cruzi, and LmLAP from Leishmania major reveals the crucial role of hydrophobic interactions in the inhibition process of these parasite metallo‐aminopeptidases.

Covalent Insertion of a Mn(Salen) Type Complex in Cross‐Linked Protein Crystals: Design of an Enantioselective Artificial Epoxidase

open access: yesChemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
An Artificial metalloenzyme was designed by a Michael addition between a MnSalen complex and a cysteine residue within NikA crystals. The heterogeneous catalyst was found capable of an enantioselective and stereospecific epoxidation of cis‐β‐methylstyrene in cristallo.
