The synthesis is described of several peptides containing the sequence Phe-Met. In order to limit enzymatic degradation and to restrict the number of possible conformations they were cyclized with variable ring size. Some unexpected side-reactions were encountered during the synthesis of the linear precursors: partial cleavage of the active ester during removal of the Bocprotecting group, partial cleavage
描述了几种含有序列Phe-Met的肽的合成。为了限制酶促降解并限制可能的构象数目,将它们以可变的环大小环化。在线性前体的合成过程中遇到了一些意想不到的副反应:在去除Bocprotection基团的过程中活性酯的部分裂解,在酯功能的肼解过程中Gly-Gly肽键的部分裂解以及未能获得p-通过DCC方法获得Boc-Phe-Met-Gly-Gly-OH的硝基苯基酯。最后,将叠氮磷酸二苯酯用于几种线性肽的环化。提到了行为活动和代谢稳定性的一些结果。
