本工作报道了新型吲唑骨架7-OTf-1H-吲唑（三氟甲磺酸1H-吲唑-7-基酯）、7-碘-1H-吲唑和3-溴-7-碘-1H-吲唑的合成。这些新化合物是通过钯交叉偶联反应发散合成吲唑的有效构件。
This work reports on the synthesis of the novel indazole scaffolds 7-OTf-1H-indazole (trifluoromethanesulfonic acid 1H-indazol-7-yl ester), 7-iodo-1H-indazole and 3-bromo-7-iodo-1H-indazole. These new compounds are potent building blocks in divergent syntheses of indazoles via palladium cross-coupling reactions.
