(Equation Presented). The total synthesis of the potent antifungal and antibiotic cyclic depsipeptide LI-F04a and its side chain epimer was accomplished using macrolactonization to assemble the cyclic peptide core, followed by attachment of the 15-guanidino-3-hydroxypentadecanoyl (GHPD) side chain. The side chain was assembled by Yamaguchi-Hirao alkylation of both enantiomers of a chiral epoxide to provide a pair of enantiomeric side chains. The attachment of both these chains to the cyclic peptide allowed the absolute configuration of the side chain hydroxyl group in LI-F04a to be assigned as (R).
