Diazonamide studies. A direct synthesis of the indole bis-oxazole fragment from tri- and tetra-peptides using biomimetic oxidative cyclizations

Sperry, Jonathan,Moody, Christopher J.

experimental part, p. 6483 - 6495 (2010/10/19)

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 viab
