An efficient diastereoselective synthesis of (−)-stemoamide has been accomplished from a pyroglutamic acid derivative in eight steps and with 24% overall yield. The synthesis features an intramolecular samarium diiodide-promoted 7-exo-trigcyclization of a ketyl radical generated from the corresponding aldehyde.
