Manganese(III) mediated oxidative free radical reactions between indole derivatives and 1,3-dicarbonyl compounds are described. In the presence of dimethyl malonate, the oxidative free radical reaction of 3-unsubstituted indoles resulted in the formation of 2-(3-oxo-2-indolylidene)malonates and these malonates can be prepared in much better yields from corresponding 3-indolecarboxylic acids. On the
介绍了锰 (III) 介导的吲哚衍生物和 1,3-二羰基化合物之间的氧化自由基反应。在丙二酸二甲酯存在下,3-未取代的吲哚的氧化自由基反应导致形成 2-(3-oxo-2-indolylidene)丙二酸,这些丙二酸可以从相应的 3-吲哚羧酸以更高的产率制备. 相反,3-未取代的吲哚与2,4-戊二酮或乙酰乙酸乙酯之间的氧化自由基反应生成呋喃[3,2-b]吲哚。
