In this study, visible-light-induced [3+2] cyclization reactions of hydrazones with hypervalent iodine diazo reagents as diazomethyl radical precursors are reported. Mild reaction conditions, a broad substrate scope, and excellent functional group compatibility were observed. Furthermore, the synthetic utility was demonstrated by gram-scale synthesis and elaboration to several value-added products. This protocol broadens the scope of diazo chemistry, and is applicable to the late-stage functionalization of natural products. (Figure presented.).
