class of naturalproducts for which chemical synthesis has no practical solution. To meet this challenge, an electrochemicaloxidativedimerization method was developed, which was applied as the pivotal step of the first total synthesis of dixiamycin B. This method is also general for N–N dimerization of substituted carbazoles and β-carbolines, providing entry into seldom explored chemical space.
N-N-连接的二聚吲哚生物碱代表了一类未开发的天然产物,化学合成没有实际解决方案。为了应对这一挑战,开发了一种电化学氧化二聚法,该方法被用作双氧霉素 B 首次全合成的关键步骤。 该方法也适用于取代咔唑和 β-咔啉的 N-N 二聚化,提供了进入很少探索化学空间。

In addition to the previously reported symmetrical beta-carboline dimer 1, an ascidian Didemnum sp. yielded trace amounts of beta-carboline and the nonsymmetrical beta-carboline dimers 2, 3, and 5. The structures of the nonsymmetrical dimers were confirmed by nonselective synthesis of 2 and 3 from beta-carboline, which also yielded additional dimers 4 and 6.
