A common and short stereoselective route is described for the formal synthesis of pyrrolizidine alkaloids, (−)-isoretronecanol and (−)-trachelanthamidine. An approach to the synthesis of indolizidine alkaloids (−)-5-epitashiromine and (−)-tashiromine utilizing ring closing metathesis is also described starting from commercially available and inexpensive l-proline.
