Description
- General description: 1-Hydroxybenzotriazole is a coupling reagent used to synthesize amides by the condensation reaction between the activated ester/acid and the amino group of protected amino acids.[1] It is also used as a racemization suppressor during peptide synthesis.[2]
- Application: 1-Hydroxybenzotriazole hydrate can be used as a condensation reagent to prepare: Poly-γ-glutamic acid methyl ester from a dimer of γ-glutamic acid.[2] Oxadiazoles via cyclo condensation of amidoximes with trifluoroacetic anhydride or benzoic acid derivatives.[3]
- Other Notes: Widely used additive to decrease racemization in the carbodiimide peptide coupling;[4] Racemization-free condensation of peptide fragments[5][6]
