Product Information

• Name: L-Threonine benzyl ester hydrochloride
• Brand: Biosynth
• Description: L-Threonine benzyl ester hydrochloride is a glycopeptide that is used as a precursor to L-threonine. It is synthesized from cycloserine, which contains a phenyl group, and D-serine, which contains an amino acid with two threonine molecules. The synthesis starts with the activation of the benzyl ester by treatment with hydrazoic acid. This activated compound reacts with D-serine in the presence of an organic base to form the benzyl ester of D-serine. The reaction can be carried out in one pot without isolation steps. The final step is an oxidative cleavage of the benzyl group by irradiation with ultraviolet light or exposure to hydrogen peroxide, yielding L-threonine benzyl ester hydrochloride as a white solid.
