Title
(EN) NEW PROCESS FOR THE ESTERIFICATION OF AMINO ACIDS
(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 alkylsulfate 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 procédé d'esterification qui consiste à soumettre un amino-acide à l'action d'un alcanol en présence d'une quantité équimoléculaire d'un sulfate d'alcoyle et à isoler l'ester sous forme d'alcoylsulfate. Les esters obtenus sont des intermédiaires de synthèse très utiles.
