Synthetic study of ustiloxin analogs: Benzylic oxidation of 13-membered cyclic peptide by lead tetraacetate

The 13-membered cyclic peptides (5,6), analogs of phomopsin-ustiloxin class of antibiotics, have been synthesized. Benzylic hydroxyl group was introduced in desired stereochemistry by lead tetraacetate oxidation followed by methanolysis.
