A dearomatization–rearomatization strategy for construction of 4H-quinolizin-4-ones via C–H bond functionalization of pyridines

Abstract

Herein, based on dearomatization-rearomatization strategy, a straightforward construction of poly-substituted and fused 4H-quinolizin-4-ones via direct ortho C-H bond functionalization of pyridines in metal-free conditions has been developed. This approach offers...
