We report the synthesis of the phosphohistidine analogue, Fmoc-4-diethylphosphonotriazolylalanine 5 and its incorporation into peptides. Our synthesis of 5 has enabled us to demonstrate that the analogue is compatible with Fmoc-solid phase peptide synthesis (SPPS) conditions. Standard cleavage conditions yield the diethyl phosphonate-protected peptide, however this can be subsequently deprotected using trimethylsilyl bromide to yield the free phosphonic acid-containing peptides.
我们报道了磷组氨酸类似物Fmoc-4-二乙基膦基三唑丙氨酸5的合成及其在多肽中的引入。我们对5的合成使得我们能够证明该类似物与Fmoc-固相多肽合成(SPPS)条件兼容。标准的切割条件产生二乙基膦酸保护的多肽,然而这可以通过使用三甲基溴硅烷随后去保护,得到含自由膦酸的多肽。
