Abstract
In accordance with the present invention, there is provided a method of preparing higher generation 1→3 C-branched polyamide dendrons. The combination of commercially available acryloyl chloride with 1→3 C-branched amines, e.g., di-tert-butyl 4-[2-(tert-butoxycarbonyl)ethyl]-4-aminoheptanedioate, resulted in generally high yields of acryl amides, which upon treatment with other reagents, generated the desired higher generation dendrons. These second and third generation dendrons were fully characterized and compared to the samples prepared from a convergent synthesis.
