Total Synthesis of Indole Alkaloid Alsmaphorazine D
Copyright policy )Total Synthesis of Indole Alkaloid Alsmaphorazine D
AbstractA concise total synthesis of rac‐alsmaphorazine D has been described for the first time. The efficient synthetic strategy features four key transformations: 1) a catalytic intramolecular oxidative cyclization for the δ‐lactamindole backbone; 2) an oxidative cyclic aminal formation for the hexahydropyrrolo[2,3‐b]pyrrole framework; 3) a transannular radical cyclization for the construction of the diazabicyclo[3.3.1]nonane structure; and 4) a one‐pot desilylation/double epimerization reaction that affirms the relative stereochemistry.
