Autoxidation of 5,6-dihydroxyindole-2-carboxylic acid () in the presence of metal ions, e.g. Co2+, leads to a mixture of oligomers, the major of which has been isolated as the acetyl and methyl ester derivative and identified as 5,6,5′,6′-tetraacetoxy-2,2′-dicarbomethoxy-4,4′-biindolyl ().
在金属离子(例如Co 2+)存在下,自动氧化5,6-二羟基吲哚-2-羧酸()会形成低聚物的混合物,其主要成分已被分离为乙酰基和甲基酯衍生物,并确定为5,6,5',6'-四乙酰氧基-2,2'-二甲氧基甲氧基-4,4'-联吲哚基()。
