Exploiting Asymmetric Nitrogen Chlorination for Construction of N -Chloroimine Atropisomers

Abstract Enantioselective halogenation has recently expanded from carbon to heteroatomic sulfur and phosphorus centers. However, asymmetric functionalization at nitrogen centers remains challenging. Herein, we report an atroposelective nitrogen-halogenation strategy that utilizes...

Designof Chiral Antimony Catalyst for Ring-OpeningReaction of Epoxides with Anilines

Abstract Pnictogen-bonding catalysis has emerged as a promising tool for noncovalent transformations; however, its application in asymmetric catalysis remains in its infancy, largely due to the scarcity of efficient chiral catalysts and activating modes. Herein, we report a new c...

Asymmetric Tellurium‐Bonding Catalysis for Mannich Reaction

ABSTRACT Chalcogen‐bonding catalysis has recently emerged as a powerful tool in organocatalysis. Nevertheless, its application in asymmetric transformations remains largely unexplored, primarily due to the scarcity of efficient chiral chalcogen‐bond donors. In this study, we repo...
