  摘要：

  新型免疫抑制剂来氟米特（1）的活性代谢物（2）已显示出抑制二氢乳清酸脱氢酶（DHODH）的作用。该酶催化从头进行嘧啶生物合成的第四步。已经合成了一系列活性代谢物2的类似物。已经发现它们在大鼠和小鼠迟发型超敏反应中的体内生物学活性与其体外DHODH效力密切相关。最有希望的化合物（3）在大鼠和小鼠胶原（II）诱导的关节炎模型中显示出活性（分别为ED50 = 2和31 mg / kg），与来氟米特相比，在人中的半衰期更短。类风湿关节炎的临床研究正在进行中。

  Catellani reaction has received substantial attention because it enables rapid multiple derivatization on aromatics. While using alkyl electrophiles to achieve ortho‐alkylation was one of the earliest applications of the Catellani reaction, ipso‐alkylation‐terminated reactions with β‐H‐containing reactants has not been realized to date. Herein, we report alkylation‐terminated Catellani reaction using alkyl

  Catellani反应已经引起了广泛的关注，因为它能够快速进行芳香族化合物的多重衍生。当使用烷基亲电子来实现邻烷基化是Catellani反应的最早的应用之一，本位与烷基化-封端的反应β -H-含有反应物还没有实现更新。在本文中，我们报道了使用烷基碳霉菌素（缩写为烷基Ge）作为亲核试剂的烷基化终止的Catellani反应。讨论了该反应中烷基Ge和烷基B（OH）2的反应性。该方法可实现与β的有效二烷基化含H的反应物，以前是Catellani反应无法获得的。
