O-(N-ACYLAMINOACYL)-2-PYRIDYLMETHYLKETOXIMES AND THEIR USE IN PEPTIDE SYNTHESIS

Preparation of Leu-enkephalin, Met-enkephalin and one analog of Leu-enkephalin by using O-(N-acylaminoacyl)-2-pyridylketoximes is described.Both the side products and the unreacted active amino acid derivatives were removed by utilizing the formation of a copper complex with 2-pyridylmethylketoxime.
