Key Points

Pyridine promotes efficient umpolung α-amination, yielding novel α-amination products.
Depyridination of (α-phenylvinyl)pyridinium facilitates product formation, demonstrating the method's effectiveness.
The study explores the reaction mechanism focusing on pyridinium salt intermediates.
Findings imply potential for this catalytic strategy to enhance synthetic organic chemistry.

Implication

Novel catalytic approach enhances α-amination in styrenes, suggesting efficient synthetic applications.

Abstract

Pyridine as a novel catalyst promotes umpolung α-amination of styrenes. Umpolung of α-C in styrene is achieved by the formation of (α-phenylvinyl)pyridinium, and depyridination will give the α-amination products. 23...
