  1,3-二芳基-2-重氮-1,3-二酮的铑催化好氧分解：机理研究及其在苯合成中的应用

  摘要：

  基于铑（II）催化的需氧分解过程，报道了1,3-二芳基-2-重氮-1,3-二酮向1,2-二芳基-1,2-二酮（苯）的转化。该反应在环境温度下发生，并且可以在氧气的气球压力下由少量羧酸的铑（5mol％）催化。此外，显示出来自O 2试剂的氧原子被掺入产物中，并且这伴随着羰基单元从起始原料的挤出。从机理上讲，建议分解可以通过类胡萝卜素的沃尔夫重排产生的乙烯酮中间体与分子氧活化后产生的过氧化铑或过氧自由基的相互作用。一组受控实验的结果支持了所提出的机制。通过使用这种新开发的策略，从相应的重氮底物以不同的收率合成了大量苯并衍生物和9,10-菲醌。另一方面，由于难以诱导初始重排，该方法不能从2-重氮-1，3-茚满二酮生成苯并环丁烯-1,2-二酮。

  摘要：

  sulfate radical anion, the utilization of this protocol in organic synthesis is rarely demonstrated. We reinvestigated selected K2S2O8-mediated known organic reactions that invariably require higher temperatures and an organic solvent. A diverse, mild functionalization and synthesis of heterocycles using the inexpensive oxidant K2S2O8 in water at room temperature is reported, demonstrating the sustainability

  虽然在室温下使用葡萄糖进行过硫酸盐活化主要集中在硫酸根阴离子的动力学研究上，但很少证明该协议在有机合成中的应用。我们重新研究了选定的 K 2 S 2 O 8介导的已知有机反应，这些反应总是需要更高的温度和有机溶剂。据报道，在室温下，使用廉价的氧化剂 K 2 S 2 O 8在水中对杂环进行了多样化、温和的功能化和合成，证明了该方法的可持续性和广泛的范围。与用于过硫酸盐活化的传统方法不同，当前方法使用天然丰富的葡萄糖作为 K 2S 2 O 8活化剂，避免使用高温、紫外线、过渡金属或碱。

  Suzuki–Miyaura coupling of heteroaryls is an important method for the preparation of compound libraries for medicinal chemistry and materials research. Although many catalysts have been developed, none of them have been generally applicable to the coupling reactions of heteroaryl chlorides and tosylates at room temperature. We discovered that a catalyst combination of Pd(OAc)2 and XPhos (2-dicyclohexylphosphanyl-2′

  杂芳基的 Suzuki-Miyaura 偶联是制备用于药物化学和材料研究的化合物库的重要方法。尽管已经开发了许多催化剂，但它们都没有普遍适用于杂芳基氯与甲苯磺酸酯在室温下的偶联反应。我们发现 Pd(OAc)2 和 XPhos（2-二环己基膦酰基-2',4',6'-三异丙基联苯）的催化剂组合可以有效地催化这些偶联。除了催化剂的选择，在含水醇溶剂中使用氢氧化物碱对于快速偶联也是必不可少的。这些条件促进了活性催化剂（XPhos）Pd0 的快速释放，并加速了催化循环中的金属转移。大多数杂芳基氯（31 个实例）和甲苯磺酸盐（17 个实例）的主要家族在室温下在几分钟到几小时内达到完全转化。该方法可以很容易地扩大规模以进行克级合成。此外，我们检查了整个反应中偶联伙伴的相对反应性。富电子杂芳基氯化物和甲苯磺酸盐的反应速度比缺电子杂芳基化合物慢，顺序为吲哚、吡咯呋喃、噻吩>吡啶。类似地，缺电子芳基硼酸的反应

  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.
