direct synthesis of 3-substituted-2H-indazole derivatives was developed in the presence of AgNO3/Na2S2O8 under mild reaction conditions. The reaction affords a series of 1,3-dicarbonyl-2H-indazoles products with yields of up to 82%. The mechanism of the strategy suggests that the reaction proceeds through a radical pathway. Moreover, this strategy provides a new protocol for the synthesis of functionalized
在温和的反应条件下,在 AgNO 3 /Na 2 S 2 O 8存在下,开发了一种直接合成 3-取代-2 H-
吲唑衍
生物的便捷策略。该反应提供了一系列 1,3-二羰基-2 H-
吲唑产物,产率高达 82%。该策略的机制表明反应通过自由基途径进行。此外,该策略为功能化 2 H-
吲唑的合成提供了新的方案。
