  • Oxadiazole cyclic peptides
    Patent number: 10703779
    Abstract: The present invention relates to cyclic amino acid molecules, in particular 1,3,4-oxadiazole containing macrocyclic peptides, and a process to produce the same. The process involves the macrocyclization of amino acids or linear peptides. Specifically, the process comprises reacting an amino acid molecule with an isocyano-iminophosphorane and an aldehyde or a ketone.
