Abstract
AbstractThe diastereoselective synthesis of the A‐B‐C tricyclic ring structure of the Stemona alkaloid stemocurtisine is described. This tricyclic precursor to the natural product was obtained in 19 steps from a known vinyl iodide. Attempts to prepare the C‐3a–C‐11 ether moiety of this alkaloid through a photochemically induced oxidative cyclization method were unsuccessful because of the cleavage of the A‐ring.
