1. A unified strategy for the biomimetic total synthesis of the spiroindimicin family of natural products was reported.
2. Key transformations include a one-pot two-enzyme-catalyzed oxidative dimerization of L-tryptophan/5-chloro-L-tryptophan to afford the bis-indole precursors chromopyrrolic acid/5′,5′′-dichloro-chromopyrrolic acid.
3. Regioselective C3′−C2′′ and C3′−C4′′ bond formation converting a common bis-indole skeleton to two skeletally different natural products were also included in the synthesis.
