AMINO ACIDS AND PEPTIDES. VIII. A WATER - SOLUBLE ACTIVE ESTER, PHENOLSULFONIC ACID DERIVATIVE

N-protected amino acid 4-phenolsulfonic acid derivative esters, such as 2,6-dibromo-4-sulfophenyl ester sodium salt, 2,6-dichloro-4-sulfophenyl ester potassium salt and 2-nitro-4-sulfophenyl ester sodium salt, were prepared.These esters are water - soluble active esters, and were applied for rhe synthesys of Leu-enkephalin.Keywords - water - soluble active ester; 2,6-dichloro-4-sulfophenyl ester; 2,6-dibromo-4-sulfophenyl ester; 2-nitro-4-sulfophenyl ester; peptide synthesis; Leu-enkephalin

AMINO ACIDS AND PEPTIDES. VII. PREPARATION AND APPLICATION OF A WATER-SOLUBLE ACTIVE ESTER, p-TRIMETHYLAMMONIOPHENYL ESTER

A water-soluble active ester, p-trimethylammoniophenyl ester iodide, and its nitro derivative were prepared from N-procteted amino acid and the corresponding phenol derivative by the dicyclohexylcarbodiimide method.The synthetic esters were applied to the synthesis of Leuenkephalin.Keywords--water-soluble active ester; p-trimethylammoniophenyl ester iodide; Leuenkephalin; peptide synthesis
