The manganese(III) initiated oxidative free radical reaction between 2-hydroxy-1,4-naphthoquinone and β-enamino carbonyl compound 2 is described. Enamine radical 5 can be generated effectively from the oxidation of enamine 2 by manganese(III) acetate. Spirolactam 3 was prepared effectively from readily available 2-hydroxy-1,4-naphthoquinone and enamine 2.
描述了由锰(III)引发的2-羟基-1,4-萘醌与β-烯氨基羰基化合物2之间的氧化自由基反应。烯胺基团5可以由烯胺2被乙酸锰(III)的氧化有效地产生。螺内酰胺3是由容易获得的2-羟基-1,4-萘醌和烯胺2有效制备的。
