The manganese(III) initiated oxidative free radical reaction between 1,4-naphthoquinones and ethyl nitroacetate is described. Nitromethyl radical 1 can be generated effectively from the oxidation of ethyl nitroacetate by manganese(III) acetate. Naphtho[2,3-d]isoxazole-4,9-diones, benzo[f]indole-4,9-diones and benzo[b]acridine-6,11-diones were prepared effectively from readily available 1,4-naphthoquinones
描述了锰(III)引发的1,4-萘醌与硝基乙酸乙酯之间的氧化自由基反应。硝基甲基自由基1可以有效地从硝基乙酸乙酯的由乙酸锰氧化而产生。从容易获得的1,4-萘醌有效地制备萘并[2,3 - d ]异恶唑-4,9-二酮,苯并[ f ]吲哚-4,9-二酮和苯并[ b ] ac啶-6,11-二酮和硝基乙酸乙酯。
