A modified benzhydrylamine - A useful handle reagent for Fmoc based solid phase synthesis of peptide amides

Abstract
Usefulness of a dimethoxybenzhydrylamine derivative, 3-(3-(Fmoc-amino-4-methoxyphenylmethyl)-4-methoxyphenyl)propionic acid, for Fmoc-based solid phase synthesis of peptide amides was demonstrated by preparation of three biologically active peptide amides, i.e. tetragastrin, neuromedin B and [8-arginine]vasopressin. 1M trimethylsilyl bromide-thioanisole (molar ratio 1 : 1) in trifluoroacetic acid was recommended as a deprotecting reagent for releasing the peptide amides from the resin.
