Description

General description

A novel derivative for the synthesis of sulfotyrosine-containing peptides by Fmoc SPPS. The sulfate neopentyl group is stable to TFA, and thus protects the sulfotyrosine residue from degradation during the cleavage reaction, but is easily cleaved post-cleavage by treatment of the peptide with aqueous ammonium acetate ^[1].
