The total synthesis of herbarumin III is described, proving the
versatility of the Prins cyclization in the synthesis of natural products.
The approach is convergent and highly stereoselective. Ring-closing
metathesis and alkene-rearrangement reactions are utilized as key
steps in the synthesis of the macrolactone.
