  钌配合物催化芳烃碳氢键与烯烃的加成反应

  摘要：

  已经发现钌配合物，例如 Ru(H)2(CO)(PPh3)3，可以以高效率和选择性催化芳族酮的邻位 C-H 键与烯烃的加成。2'-甲基苯乙酮与各种类型的末端烯烃反应，以良好至极好的产率产生 1:1 偶联产物。C-C 键的形成仅发生在烯烃的末端碳原子上，但苯乙烯除外，它提供两种区域异构体的混合物。乙酰萘、环状芳族酮和杂芳族酮也与三乙氧基乙烯基硅烷反应以几乎定量的产率产生 1:1 的加成产物。从 2'-乙酰萘或 3-乙酰噻吩（其中有两个不同的反应位点），只能获得四种可能的区域异构体中的一种。提出了酮的氧原子与钌的配位和环金属化中间体的介入的重要性。使用苯乙酮-d5 和三乙氧基乙烯基的氘标记实验...

  Ru(H)2(CO)(PPh3)3, have been found to catalyze the addition of ortho C–H bonds of aromatic ketones to olefins with a high degree of efficiency and selectivity. 2′-Methylacetophenone reacts with various types of terminal olefins to give 1 : 1 coupling products in good to excellent yields. The C–C bond formation takes place exclusively at the terminal carbon atom of olefins except for styrene which affords a mixture

  The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The recent development of a modular synthesis of tetracycline analogs through a chiral enone intermediate has allowed for the efficient synthesis of novel tetracycline analogs never prepared before. The present invention provides a more efficient route for preparing the enone intermediate.

  四环素类抗生素已经在过去50年的传染病治疗中发挥了重要作用。然而，四环素在人类和兽医医学中的广泛使用导致许多之前对四环素抗生素敏感的生物体产生了抗药性。最近，通过手性烯酮中间体的模块化合成，成功地合成了以前从未制备过的新型四环素类似物。本发明提供了一种更有效的制备烯酮中间体的方法。

  The present disclosure relates to bifunctional compounds, which find utility as modulators of Kirsten rat sarcoma protein (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand which binds to the respective E3 ubiquitin ligase and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation, accumulation, and/or overactivation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

  本公开涉及双功能化合物，它们可用作 Kirsten 大鼠肉瘤蛋白（靶蛋白）的调节剂。特别是，本公开涉及双功能化合物，其一端含有与相应 E3 泛素连接酶结合的 Von Hippel-Lindau、cereblon、Apotosis Proteins 抑制剂或小鼠双敏同源物 2 配体，另一端含有与靶蛋白结合的分子，从而使靶蛋白靠近泛素连接酶以实现对靶蛋白的降解（和抑制）。本公开物具有与降解/抑制靶蛋白相关的广泛药理活性。本公开的化合物和组合物可以治疗或预防因目标蛋白的聚集、积累和/或过度激活而导致的疾病或失调。

  The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The modular synthesis of tetracyclines and tetracycline analogs described provides an efficient and enantioselective route to a variety of tetracycline analogs and polycyclines previously inaccessible via earlier tetra-cycline syntheses and semi-synthetic methods. These analogs may be used as anti-microbial agents or anti-pro liferative agents in the treatment of diseases of humans or other animals.
