Abstract

A review of synthetic methods of peptide substrates containing aminonaphthalenesulphonamide (ANSA) as the detected leaving group is presented. Variations of aminoacylic and peptide ANSA derivatives using ANSA as the C-protect group at all stages of the peptide synthesis, condensations of the ANSA with the N-protected peptide fragment obtained preliminary, the application of aminoacyl-ANSA as syntones are discussed. The synthesis scheme used while determining optimal ANSA substrates that involves reactions of aminoacyl derivatives of aminonaphthalenesulfonylchlorides with amines is shown. The application of di-tert-butylpyrocarbonate, DCC, chlorodimethylformiminium chloride, alkylchloroformate as condensing agents is described. The protection of amino groups was carried out by using Boc- and Cbz- groups.
