Catalytic Metal-Free Intramolecular Acylcyanation: Synthesis of Functionalized Pyridine Derivatives Bearing Pendent Stereocenters.

A novel protocol for the synthesis of functionalized pyridines containing quaternary carbon centers through a metal-free catalytic intramolecular acylcyanation approach has been developed. Broad scope, versatility, and efficiency of the process was demonstrated. [ABSTRACT FROM AUTHOR]
