标题:通过硼酸催化从α-氨基酸衍生的惰性酯形成羟基引导的肽键
摘要:描述了硼酸催化 α-氨基酸甲酯形成肽键.该催化对 β-羟基-α-氨基酯表现出高化学选择性,使肽具有高至优异的收率和高官能团耐受性.这种羟基定向的肽键形成可适用于寡肽合成.这是有机硼催化α-氨基酸衍生的惰性酯形成肽键的第一个成功例子.

标 题 :Synthesis of hpGRF(Somatocrinin) in liquid phase and intermediate peptides
发明人：DIAZ JOSEPH; DEMARNE HENRI; RONCUCCI ROMEO; SCHMELCK PAUL-HENRY
权利人:SANOFI SA
摘要:The invention relates to synthesis of hpGRF (Somatocrinin) in liquid phase and to intermediate peptides, comprising: coupling, one after the other and in the order of the sequence of the GRF, the fragments in which: (a) the side acid functions of the aspartic and glutamic acids and the side amine function of the lysine are protected by protector groups stable in the conditions of deprotection of the group Boc, (b) the guanidine function of the arginine is protected by protonation, and (c) the N-terminal amino acid is protected on the amine by the Boc group; selectively eliminating the group Boc from the N-terminal amine of the peptide in phase of elongation by hydrolysis with trifluoroacetic acid, said coupling being effected in an aprotic polar solvent and eliminating, at the end of sequence, all the protector groups by hydrolysis with the aid of a 0.1 to 1M solution of methanesulfonic or trifluoromethanesulfonic acid in trifluoroacetic acid.
