Convenient Four-Step Synthesis of H-Pyr-His-Trp-OH, a Key Tripeptide Intermediate for the Production of Synthetic Gonadoliberin Agonists

Resumo

An effective four-step synthesis of the tripeptide H-Pyr-His-Trp-OH that is used to produce synthetic gonadoliberin agonists was developed. The synthesis was carried out without adding and removing protecting groups and could produce the target compound with >98% purity.
