Dendritic polyamides with polydispersity of 1.1-1.4 have been successfully prepared from trimesic acid, 5-aminoisophthalic acid, and 4-aminophenylpropionic acid as a core molecule, a dendron, and a spacer unit, respectively, with a one-pot procedure. This procedure involves successive activation of

β¦ Synopsis
The selective reactions of aliphatic imidazolides have been utilized in the convergent synthesis of polyamide dendritic wedges and dendrimers. Steric problems were overcome by increasing the size of the triamine branch unit and using a bifunctional core molecule. Three generations of wedges and dendrimers have been prepared with masses of up to 3999 daltons.
