A short and efficient synthesis of seco-duocarmycin SA (3), a highly potent cytostatic agent and direct precursor of the natural product duocarmycin SA (1), has been achieved. Starting from commercially available 2-methoxy-4-nitroaniline (4) the synthetic protocol contains a Fischer indole synthesis to introduce the heterocyclic scaffold and a radical 5-exo-trig cyclization to furnish the (chloromethyl)indoline ring system as key reactions.
