  Bromo-Boronolactonization of Olefins¹

  摘要：

  Exposure of a variety of mono- and disubstituted ortho-alkenylarylboronic acids to NBS in THF/ H2O under neutral conditions affords bromo-boronolactones, in some instances, with exceptional regiocontrol. The adducts, analogous to those formed by carboxylic acids, are shown to be useful synthetic intermediates.

  The present invention describes 2-methyl-quinazoline compounds of general formula (I), methods of preparing said compounds, intermediate compounds useful for preparing said compounds, pharmaceutical compositions and combinations comprising said compounds, and the use of said compounds for manufacturing pharmaceutical compositions. The 2-methyl substituted quinazoline compounds of general formula(I) effectively and selectively inhibit the Ras-Sos interaction without significantly targeting the EGFR receptor. They are therefore useful for the treatment or prophylaxis of diseases, in particular of hyperproliferative disorders, such as cancer as a sole agent or in combination with other active ingredients.

  本发明描述了一般式(I)的2-甲基喹唑啉化合物，制备该化合物的方法，用于制备该化合物的中间体化合物，包含该化合物的药物组合物和组合物，以及用于制造药物组合物的该化合物的用途。一般式(I)的2-甲基取代喹唑啉化合物有效且选择性地抑制Ras-Sos相互作用，而不显著靶向EGFR受体。因此，它们对于治疗或预防疾病特别是高增殖性疾病，如癌症作为单一药剂或与其他活性成分组合使用是有用的。

We demonstrate that it can be combined with metal–halogen exchange reactions or a variety of directed ortho metalation protocols in a “one-pot” sequence for the synthesis of aromatic amines with unique substitution patterns.

  通过使用常见的廉价亲电氮源（H 2 N-OSO 3H，HSA）。通过这种方法发现富含电子的底物具有最高的反应性。但是，在室温条件下，即使是中等电子贫乏的基材也能很好地耐受。与不受阻碍的基材相比，受阻的基材似乎同样有效。高度缺乏电子的底物在室温下以非常低的产率提供产物，但是在回流温度下获得中等至良好的产率。我们的方法也适用于几种常见的硼酸衍生物（例如频哪醇酯）的亲电胺化反应。我们证明了它可以与金属-卤素交换反应或各种定向的邻位金属化方案以“一锅”顺序结合使用，以合成具有独特取代模式的芳香胺。DFT研究，结合实验结果，表明该反应是通过碱介导的HSA活化发生的，然后发生1,2芳基B–N迁移。这种活化方式对于反应的成功似乎至关重要，并且首次允许在环境温度下对硼酸进行一般的亲电子胺化。

  This work reports a green method for the synthesis of aryl selenocyanates via a three‐component reaction of arylboronic acids, Se powder, and trimethylsilyl cyanide (TMSCN) under metal‐free and additive‐free conditions. Remarkably, TMSCN acts as not only the substrate, but also the catalyst. Various selenaheterocycles can be also accessed with a catalytic amount of TMSCN.
