under relatively mild acidic conditions. Using these building blocks, despite the bulkiness of the adamantyl group, no particular problem of coupling was observed during the solid-phase synthesis of phosphinic peptides by the Fmoc strategy. The developed methodology is of particular interest to facilitate the development of potent inhibitors of zinc-metalloproteases.
为了发展次膦肽的固相合成,已制备了不同的FmocXaaPsi PO(OAd)CH(2)} XaaOH构件,其中Fmoc是(芴基甲氧基)羰基。在这方面,事实证明通过金刚烷基保护这些次膦酸二肽中的羟基次膦酰基官能是方便的。次膦金刚烷基酯在碱性条件下是完全稳定的,并且可以在相对温和的酸性条件下除去。使用这些结构单元,尽管金刚烷基的体积很大,但在通过Fmoc策略固相合成次膦肽期间未观察到特别的偶联问题。所开发的方法学特别有助于促进锌金属蛋白酶的有效抑制剂的开发。
