3-Alkyl/aryl-1H-indazoles and 3-alkyl/aryl-3H-indazole-3-phosphonates were synthesized efficiently through a 1,3-dipolar cycloaddition reaction between α-substituted α-diazomethylphosphonates and arynes under simple reaction conditions. The product distribution was controlled by the phosphoryl group, which acted both as a tuning group and a traceless group in the reaction.

通过磷酰基调节的3-取代的1 H-吲唑和3,3-二取代的3 H-吲唑-3-膦酸酯的可切换合成

在简单的反应条件下，通过α-取代的α-重氮甲基膦酸酯和芳烃之间的1,3-偶极环加成反应，可以高效合成3-烷基/芳基-1 H-吲唑和3-烷基/芳基-3 H-吲唑-3-膦酸酯。 。产物分布由磷酰基控制，该磷酰基在反应中既充当调节基团又充当无痕基团。
