均苯三酚(1)是合成黄酮类药物的中间体,其合成路线报道较多。有用2,4,6-三硝基甲苯为原料的工业化生产法[1],原料便宜,生产工艺成熟,但污染环境、后处理较难;另有以2,4,6-三硝基苯甲酸或1,3,5-三异丙基苯为原料的报道[2,3],但原料难得;还可以苯或三硝基苯制备1[4]。我们参... Pyrogallol (1) is an intermediate of synthetic flavonoids, and its synthesis route is reported more. Use of 2,4,6-trinitrotoluene as raw material for industrial production [1], cheap raw materials, production technology is mature, but polluting the environment, post-processing more difficult; another 2,4,6-trinitrobenzene Formic acid or 1,3,5-triisopropylbenzene as a raw material [2,3], but the raw materials rare; benzene or trinitrobenzene can also be prepared 1 [4].
