合成路线1
该中间体在本合成路线中的序号：(XXII)The synthesis of the precursor peptide (XVII) was also reported in solution phase. trans-4-Hydroxy-L-proline (XX) was protected as the N-Boc derivative (XII), which was subsequently activated as the pentafluorophenyl ester (XXI). This was condensed with the dipeptide alanyl-serine (XXII) to furnish the protected tripeptide (XXIII). Acidic cleavage of the Boc protecting group of (XXIII) yielded tripeptide (XXIV).
