Patent ID: 8586705

Claim:
A process for preparing a macromolecule, wherein the macromolecule comprises at least one dendritic motif; which process includes: (i) providing a growing macromolecule including at least one reactable amine group; a first building compound having a hydrocarbon backbone, and bearing an apex carbonyl group and having a first amino group bearing a first functional moiety and a second amino group bearing a second functional moiety, wherein the first and second functional moieties are different, and wherein the first and second functional moieties are attached to the first and second amino groups, optionally through a linker, by an amide bond; (ii) activating the apex carbonyl group of the first building compound; and (iii) reacting the at least one reactable amine group of the growing macromolecule with the activated apex carbonyl group of the first building compound.
