A diketone linchpin 1,5-dichloropentane-2,4-dione converts peptide libraries displayed on phage to 1,3-diketone bearing macrocyclic peptides (DKMP): shelf-stable precursors for Knorr pyrazole synthesis. Ligation of diverse hydrazine derivatives onto DKMP libraries displayed on phage that carries silent DNA-barcodes yields macrocyclic libraries in which the

    The present invention relates to a method of forming a macrocyclic peptide bearing a pharmacophore and said produced macrocyclic peptide, wherein the method comprises the steps of: reacting a peptide with two thiol groups of cysteine side chains with the reactive compound 1,5 -dichloropentanedion-2,4. The reaction between the reactive compound and the peptide produces an 1,3 -diketone-containing macrocyclic polypeptide. The macrocycle with a 1,3 -diketone group is then modified by reaction of said macrocycle with an alkyl or aryl hydrazine group bearing a pharmacophore in benign aqueous conditions. The macrocycles may be displayed in a library, such as a phage display library, and used to biopan for affinity against a selected target.

    The twofold ring‐closing metathesis of homoallyl crotonate and homoallyl ethenesulfonate intermediate A gave unsaturated lactone and sultone containing intermediate B. The lactone was modified by diastereoselective 1,4‐addition of a silyl cuprate and the sultone was removed to deliver a homoallylic alcohol that iodocarbonatized cis‐selectively (→ C).
