Practical and highly stereoselective approaches to the total synthesis of (-)-codonopsinine

The enantiopure total synthesis of (-)-codonopsinine is described using two effective chiron approaches starting either from commercially available l-xylose or from readily available Garner aldehyde. The key steps included Julia trans-olefination, highly
