General description

An excellent building block for the preparation of phosphotyrosine-containing peptides [1] by Fmoc SPPS. This derivative can be introduced using standard activation methods, such as PyBOP® and TBTU. Using this reagent, even peptides containing multiple phosphorylation sites have been prepared efficiently by standard Fmoc SPPS methods [1].
