Abstract
Derivatives of 1-phenyl pyrazolin-5-one have many applications for biomolecule synthesis. Enol esters of protected amino acids made by the present process provide efficient coupling in solid-phase peptide synthesis. The 1-phenyl-pyrazolin-5-one derivatives are highly crystalline, stable, non-toxic and easy to prepare. Many possess self-indicating properties, facilitating spectrophotometric monitoring and automation of peptide synthesis.
