Photocatalytic radical cyclization of α-halo hydrazones with β-ketocarbonyls: Facile access to substituted dihydropyrazoles

Abstract

A mild and efficient method for the photocatalytic radical cyclization of α-halo hydrazones with β-ketocarbonyls has been described. This strategy provides a potential protocol for the construction of functionalized 4, 5-dihydropyrazoles in moderate to high yields.
