oxidation of several readily prepared tryptophan containing tri- and tetrapeptides with DDQ results in a biomimeticcyclization and directformation of the indole bis-oxazole fragment of diazonamide A, establishing that such a transformation is a viable route when considering the biosynthetic formation of the heterocyclic core of the natural product.
