Concise total synthesis of (±)-aspidospermidine

Org Biomol Chem. 2015 May 14;13(18):5255-9. doi: 10.1039/c5ob00228a.

Abstract

(±)-Aspidospermidine (1) has been synthesized from the commercially available 2,3-dihydro-1H-carbazol-4(9H)-one 6 in 10 steps with 20% overall yield. The key step of the strategy is a one-pot carbonyl reduction/iminium formation/intramolecular conjugate addition reaction that may be applied for the synthesis of other Aspidosperma alkaloids.
