has previously been shown to reverse the formation of neurotoxic fibrils associated with Alzheimer's disease. We have developed a synthetic route to DAPH and structurally related analogues that employs palladium-catalyzed amination as the key bond-forming step. The requisite substrates are easily obtained, and their coupling with substituted anilines proceeds in generally high yields. Thus, a variety
DAPH(4,5-二苯并邻苯二甲酰亚胺)先前已被证明可以逆转与阿尔茨海默氏病相关的神经毒性原纤维的形成。我们已经开发了一种合成DAPH和结构相关类似物的合成途径,该途径采用钯催化的胺化作用作为关键的键形成步骤。容易获得所需的底物,并且它们与取代的苯胺的偶联通常以高收率进行。因此,可以以模块化方式快速访问各种DAPH类似物。另外,本文描述的途径也应适合于将其他种类的亲核试剂掺入分子框架。
