The total synthesis of ustiloxin D, a highly potent inhibitor of microtubule assembly, has been achieved. Notable features are the use of nucleophilic aromatic substitution (SNAr) for the construction of a chiral tertiary alkyl-aryl ether linkage, Sharpless asymmetric aminohydroxylation for the formation of the beta-hydroxytyrosine moiety, macrolactamization, and regioselective methylation.
