Title
(FR) NOUVEAU PROCEDE D'ESTERIFICATION D'AMINO-ACIDES
Abstract
(EN) The invention relates to the field of the peptide chemistry. The object is an esterification process which comprises subjecting an amino acid to the action of an alkanol in the presence of an equimolecular amount of an alkylsulfate and isolating the ester in the form of alkylsulfate. The esters obtained are very useful synthesis intermediate products.
(FR)

L'INVENTION SE RAPPORTE AU DOMAINE DE LA CHIMIE DES PEPTIDES. ELLE A POUR OBJET UN PROCEDE D'ESTERIFICATION QUI CONSISTE A SOUMETTRE UN AMINO-ACIDE A L'ACTION D'UN ALCANOL EN PRESENCE D'UNE QUANTITE EQUIMOLECULAIRE D'UN SULFATE D'ALCOYLE ET A ISOLER L'ESTER SOUS FORME D'ALCOYLSULFATE. LES ESTERS OBTENUS SONT DES INTERMEDIAIRES DE SYNTHESE TRES UTILES.
