Application of the palladium(0)-catalyzed ullmann cross-coupling reaction in a total synthesis of (±)-aspidospermidine and thus representing an approach to the lower hemisphere of the binary indole-indoline alkaloid vinblastine

As part of ongoing studies directed towards the construction of the anti-cancer agent vinblastine (1), the related but structurally less complex natural product aspidospermidine (3) has been synthesized. Two approaches to target 3 were pursued. In the fir
