Solid-Phase Synthesis of 1,3-Azole-Based Peptides and Peptidomimetics
摘要:
[graphics]We report highly efficient two-step procedures for the synthesis of 1,3-oxazole-, thiazole-, and imidazole- containing peptides on solid phase from dipeptides composed of C-terminal threonine, serine, cysteine, or diaminopropionic acid by using different cyclodehydration procedures followed or preceded by oxidation. The methods are compatible with Fmoc solid-phase peptide synthesis conditions and with N-Fmoc, N-Boc, N-Cbz, and N-Alloc protecting groups.
