Synthesis of diamido gellants by using amino acid N-carboxyanhydrides |
摘要 |
The invention relates to a method for the synthesis of a compound according to formula I comprising the following steps: a) reacting a N-carboxyanhydride according to formula II and a N-carboxy-anhydride according to formula III with a diamine according to formula IV and b) adding an acid to the reaction to adjust the pH value of the reaction to <7; wherein L represents a C2-C20 alkyl group, a C6-C20 aryl group, or a C7-C20 alkylaryl group; and R1 and R2 can be identical or different and represent a hydrogen atom, a C1-C4 alkyl group, a C1-C4 hydroxyalkyl group, a C1-C4 thioether group, a C6-C20 aryl group, a C7-C20 alkylaryl group, a C7-C20 alkylhydroxyaryl group, a C4-C20 alkylheteroaryl group with 1 to 4 heteroatoms; or a C1-C4 alkylcarboxylic moiety, which may be an acid, an amide, or which may be esterified with a C1-C6 alkyl group or a C7-C20 alkylaryl group. |
