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.
根据本发明,提供了一种制备高代1→3 C支化聚酰胺树状分子的方法。商业上可获得的
丙烯酰氯与1→3 C支化胺(例如,叔丁基二-[2-(叔丁氧羰基)乙基]-4-
氨基
庚二酸二叔丁酯)的组合通常产生高产率的
丙烯酰酰胺,经过其他试剂的处理后,生成所需的高代树状分子。这些第二和第三代树状分子已经完全表征并与从收敛合成中制备的样品进行了比较。
