Abstract:
Azomethine imines, as a prominent class of 1,3‐dipolar species, hold great significance and potential in organic and medicinal chemistry. However, the reported synthesis of centrally chiral azomethine imines relies on kinetic resolution, and the construction of axially chiral azomethine imines remains unexplored. Herein, we present the synthesis of axially chiral azomethine imines through copper‐ or chiral phosphoric acid catalyzed ring‐closure reactions of N ′‐(2‐alkynylbenzylidene)hydrazides, showcasing high efficiency, mild conditions, broad substrate scope, and excellent enantioselectivity. Furthermore, the biological evaluation revealed that the synthesized axially chiral azomethine imines effectively protect dorsal root ganglia (DRG) neurons by inhibiting apoptosis induced by oxaliplatin, offering a promising therapeutic approach for chemotherapy‐induced peripheral neuropathy (CIPN). Remarkably, the ( S )‐ and ( R )‐atropisomers displayed distinct neuroprotective activities, underscoring the significance of axial stereochemistry.
