Significance

Minfiensine is isolated from the African plant Strychnos minfiensis. The authors present two strategies for conversion of the intermediate F into the target molecule. The markworthy step of the synthesis is a tandem enantioselective intramolecular Heck iminium ion cyclization (C → E → F). For another recent synthesis of ()-minfiensine see: L. Shen, M. Zhang, Y. Wu, Y. Qin, ­Angew. Chem. Int. Ed. 2008, 47, 3618.
