## Abstract The syntheses are described of glycyl‐α‐L‐aspartyl‐L‐serylglycine ethyl ester and of the O‐acetylated derivative. The tetrapeptide ethyl esters were obtained by coupling two dipeptide derivatives using the mixed anhydride method, followed by removal of the blocking groups. The dipeptide

## Abstract The syntheses of glycyl‐α‐L‐glutamyl‐L‐serylglycine ethyl ester and of glycyl‐α‐L‐glutamyl‐O‐acetyl‐L‐serylglycine ethyl ester are described. The mixed anhydride method and the carbodiimide method were used for condensing together two dipeptide derivatives. The latter were obtained by t
