Preparations of aza analogues of known potent growth hormone secretagogues (GHS) were unsuccessful using known methods for preparation of azapeptides when hindered amines were employed. We now report a coupling method using bispentafluorophenylcarbonate as a “balanced reactivity” phosgene equivalent to solve these problems.
当使用受阻胺时,使用已知的制备氮杂肽的方法不能成功制备已知有效生长激素促分泌素(GHS)的氮杂类似物。现在,我们报告使用双五氟碳酸苯酯作为“平衡反应性”光气等同物的偶联方法,以解决这些问题。
