Title
(EN) REDUCTIVE ALKYLATION PROCESS FOR THE PREPARATION OF COMPOUNDS CONTAINING AT LEAST TWO AMINO GROUPS
(FR) PROCEDE D'ALKYLATION REDUCTEUR SERVANT A LA PREPARATION DE COMPOSES CONTENANT AU MOINS DEUX GROUPES AMINES
Abstract
(EN)
An alkylation process is described. The process comprises reacting at least a first nitrogen compound and a second nitrogen compound with a carbonyl compound in the presence of a reducing agent to form a product comprising at least two nitrogen groups; wherein the carbonyl compound comprises at least two carbonyl groups, the first nitrogen compound comprises a first nitrogen group reactive with one carbonyl group of the carbonyl compound and the second nitrogen compound comprises a second nitrogen group reactive with the other (or another) carbonyl group of the carbonyl compound, and wherein at least the first nitrogen compound or at least the second nitrogen compound comprises at least one other functional group. The process is especially suitable for the preparation of (S,S)-ethylenediaminedisuccinic acid (EDDS) of formula (1).
(FR)
Cette invention concerne un procédé d'alkylation. Ce procédé consiste à faire réagir au moins un premier composé azoté et un second composé azoté avec un composé carbonyle en présence d'un agent réducteur de façon à former un produit comportant au moins deux groupes azotés. Ledit composé carbonyle comporte au moins deux groupes carbonyle, le premier composé azoté comporte un premier groupe azoté pouvant réagir avec un groupe carbonyle du composé carbonyle et le second composé azoté comporte un second groupe azoté pouvant réagir avec l'autre (ou un autre) groupe carbonyle du composé carbonyle, le premier composé azoté au moins ou le second composé azoté au moins comportant au moins un autre groupe fonctionnel. Ce procédé convient particulièrement à la préparation de l'acide (S,S)-éthylènediaminedisuccinique représenté par la formule (1).
