Abstract:

In order to prepare pyrimidine nucleoside-peptide conjugate concisely, we developed a one-pot synthetic strategy. Started from uridine, 5-S-acetyl-thiomethyl-2',3'-di-O-isopropylidene-uridine (4) was synthesized as the key intermediate in four steps. Under acidic condition, compound 4 was deprotected and reacted with PySS-R (8, 12, 15, Py = 2-pyridyl, R = amino acid or peptide) in one pot to form uridine conjugates (9, 13, 2) with disulfide bond as linker.

Key words: Nucleoside-peptide conjugate, Nucleoside-peptide conjugate, Thiol exchange, Thiol exchange, Disulfide bond formation, Disulfide bond formation
