Preparation of new monomers aza-β3-aminoacids for solid-phase syntheses of aza-β3-peptides
摘要:
The preparation of new NO-Fmoc-protected aza-beta(3)-amino acids (aza-beta(3)-aa) with proteinogenic side chains as well as their N-beta-Fmoc, N-beta-Cbz or N-beta-Boc aza-beta(3)-amino esters (from Pro, Asn, Asp, Glu, Gln) by successive nucleophilic substitutions will be described.
