Chiral Phosphoric Acid Catalyzed Intermolecular [4+2] Cycloaddition for Chiral Azomethine Imines: Mechanism and Stereochemical Model

Azomethine imines are an outstanding class of 1,3-dipolar species that are important synthetic building blocks for di-nitrogenated heterocycles. Despite their significance, the current synthesis of chiral azomethine imines relies on...
