Andreas Pingel Keuth

Hi, this is a cyclic peptide. There are lot of informations for synthetic routes for those kind of molekules, My expiriences are to old (> 40 years old) there are today far better methods available.

Best Regards Andreas

Philippe Roger Bovy

Your cyclic peptide also includes a thiazole.
