资源简介：
Stable phosphohistidine (pHis) analogues which can be incorporated into peptides are valuable tools for the study of pHis in a biological context. The phosphopyrazolyl side chain has proved useful in the generation of selective τ-pHis antibodies. To allow potential incorporation of the phosphopyrazolyl side chain to peptides a N-Fmoc dibenzyl pyrazole phosphonate building block <b>3</b> was synthesized. N-Fmoc dibenzyl pyrazole phosphonate <b>3</b> was accessible in four synthetic steps using the Hirao cross coupling reaction via a P-aryl bond formation, and Vederas Boc-β-lactone <b>11</b> opening reaction to give the protected amino acid.
