Patent

CA 2421439

The invention relates to the production of compounds containing one or several groups of general formula (I) -CH2-CH(NR1R2)- with R1 = R2, or independently = H, C1-20 alkyl, C6-18 aryl, C7-20 alkaryl, C7-20 aralkyl or a polyamino group, by reductive amination of compounds, containing one or several groups of general formula (II), -CH2-CH(O-C(O)-R3)- with R3 = H, C1-20 alkyl, C6-18 aryl, C7-20 alkaryl, or C7-20 aralkyl with amines of general formula (III), HNR1R2 and hydrogen.

L'invention concerne la production de composés contenant un ou plusieurs groupes de formule générale (I) -CH¿2?-CH(NR?1¿R?2¿)- dans laquelle R?1¿ est égal à R?2¿ ou R?1¿ et R?2¿ représentent indépendamment l'un de l'autre hydrogène, alkyle C¿1-20?, aryle C¿6-18?, alkaryle C¿7-20?, aralkyle C¿7-20? ou un reste polyamine. Cette production s'effectue par amination réductive de composés contenant un ou plusieurs groupes de formule générale (II), -CH¿2?-CH(O-C(O)-R?3¿)- dans laquelle R?3¿ représente hydrogène, alkyle C¿1-20?, aryle C¿6-18?, alkaryle C¿7-20?, aralkyle C¿7-20? au moyen d'amines de formule générale (III) HNR?1¿R?2¿ et d'hydrogène.
