摘要

The oxidation of several readily prepared tryptophan containing tri-and tetrapeptides with DDQ results in a biomimetic cyclization and direct formation 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.
