A formal synthesis of the callipeltoside aglycone.
A synthesis of the macrocyclic core structure of callipeltoside A and a C9 epimer has been achieved by applications of chiral vinylzinc or Kishi-Nozaki-Hiyama (K-N-H) additions, Roskamp homologations, and acylketene or intramolecular K-N-H macrolactonizations as key bond-forming steps.
