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
在这项研究中,报道了visible与高价碘重氮试剂作为重氮甲基自由基的前体在可见光下诱导的[3 + 2]环化反应。观察到温和的反应条件,广泛的底物范围和出色的官能团相容性。此外,合成效用通过克规模的合成以及对几种增值产品的精心阐述得到了证明。该方案扩大了重氮化学的范围,适用于天然产物的后期功能化。
