A Modified Benzhydrylamine as a Handle Reagent for the Solid Phase Synthesis of Peptide Amides Based on the Fluorenylmethoxycarbonyl Method
An easily preparable dimethoxybenzhydrylamine derivative, 3-(α-Fmoc-amino-4-methoxybenzyl)-4-methoxyphenyl propionic acid (Fmoc=fluoren-9-ylmethoxycarbonyl) is a useful precursor of the C-terminal amide, when applied to Fmoc-based solid phase peptide synthesis; as a cleavage reagent from the resine, thioanisole-mediated trimethylsilyl bromide in trifluoroacetic acid is recommended.
