Facile ring-opening of N-acylisatins for the development of novel peptidomimetics

A range of novel mono- and bis-glyoxylamide peptidomimetics were prepared via the facile ring-opening of N-acylisatins with amino acids and peptide derivatives. The ring-opening of N-acylisatins with dipeptides and tripeptides was discovered to be the most efficient strategy for the synthesis of second and third generation glyoxylamides.
