We have developed an efficient method for preparation of triazolamers using a dicobalt hexacarbonyl complex of propargyl azides (CPA) as a synthetic component. Several types of CPAs possessing the side chains found in the natural amino acids were prepared by Nicholas reaction as well as by a reaction of propargyl azides with dicobalt octacarbonyl. Triazolamers with both amino and carboxyl termini were
我们已经开发了一种有效的方法,该方法使用炔丙基叠氮化物(CPA)的二钴六羰基配合物(CPA)作为合成组分来制备三唑酰胺。通过尼古拉斯(Nicholas)反应以及通过炔丙基叠氮化物与二羰基八羰基二羧酸的反应来制备几种具有在天然氨基酸中发现的侧链的CPA。具有氨基和羧基末端的三偶氮唑类很容易通过重复反应序列合成,所述重复反应序列包括铜催化的1,3-偶极环加成,然后进行氧化脱保护。
