Fmoc-D-Tyr(PO(OBzl)OH)-OH

An excellent building block for the preparation of D-phosphotyrosine-containing peptides by Fmoc SPPS. This derivative can be introduced using standard activation methods, such as PyBOP^® and TBTU. The monoprotected phosphoserine residue once incorporated is stable to piperidine. Using this reagent, even peptides containing multiple phosphorylation sites can be prepared efficiently by standard Fmoc SPPS methods.
