Well‐Defined Anilido–Imine Iron(II) Complexes for Catalytic Intramolecular Alkene Hydroamination of Primary Amines

European Journal of Organic Chemistry, EarlyView.
We synthesize and characterize a series of well‐defined anilido–imine Fe(II) alkyl complexes that demonstrate high activity and selectivity in the cyclohydroamination of unprotected primary amines tethered to unactivated alkenes. By tuning the steric and electronic parameters of the anilido–imine ligand, we develop a catalyst that outperforms ...

Alkyl Arylacetates in Cascade Reactions with 2‐Cyanobenzaldehydes for the Synthesis of 3‐Substituted Isoindolinones

European Journal of Organic Chemistry, EarlyView.
Effective synthesis of 3‐substituted isoindolinones is possible through novel cascade reactions of alkyl arylacetates with 2‐cyanobenzaldehydes under mild, basic conditions. Herein we report the use of alkyl arylacetates as pro‐nucleophiles in cascade reactions with 2‐cyanobenzaldehydes leading to the formation of novel 3‐substituted isoindolinones, a ...

One‐Pot Gold(I)‐Catalyzed Rautenstrauch Rearrangement/Nitrosocarbonyl Hetero‐Diels–Alder Reaction Sequence for the Synthesis of α‐Hydroxylated Cyclopentenones

European Journal of Organic Chemistry, EarlyView.
The regio‐ and stereoselective synthesis of ring‐fused α‐hydroxy‐2‐cyclopentenones is achieved by a one‐pot gold(I)‐catalyzed Rautenstrauch rearrangement/nitrosocarbonyl hetero‐Diels–Alder reaction/ring opening sequence carried out on suitable propargyl esters followed by selective NO bond cleavage.

Probing Chiral Recognition on Amylose Tris(3,5‐Dimethylphenylcarbamate) Using Cinnamyl 2‐Aminoanilides: The Subtle Impact of Aliphatic Substituents

ELECTROPHORESIS, EarlyView.
This study investigates how subtle aliphatic substituent differences in racemic cinnamyl 2‐aminoanilides affect chiral recognition on amylose tris(3,5‐dimethylphenylcarbamate). Pronounced enantioselectivity changes arose from minimal structural variations. Mobile phase effects were examined, with 2‐propanol improving resolution.

Cyclodextrins as Chiral Selectors in Capillary Electrophoresis—Recent Developments in Understanding Analyte Complexation and Applications in Pharmaceutical Analysis

ELECTROPHORESIS, EarlyView.
Cyclodextrins are the most often applied chiral selectors in CE enantioseparations. In combination with NMR spectroscopy and molecular modeling, studies for an understanding of chiral recognition underlying enantioseparations have been performed.

Monitoring and Mitigation Strategies for Hazardous Compounds in Chinese Rice Wine (Huangjiu): A Comprehensive Review

Food Safety and Health, EarlyView.
This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.
