  The present disclosure relates to bifunctional compounds, which find utility as modulators of Interleukin-1 Receptor-Associated Kinase 4 (IRAK-4); the target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hppel-Lindau, cereblon, ligand which binds to the 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 or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

  The description relates to cereblon E3 ligase binding compounds, including bifunctional compounds comprising the same, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present disclosure. In particular, the description provides compounds, which contain on one end a ligand which binds to the cereblon E3 ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. Compounds can be synthesized that exhibit a broad range of pharmacological activities consistent with the degradation/inhibition of targeted polypeptides of nearly any type.

  N-methylated compounds over different catalysts. Herein, we report the selective synthesis of formamides, 1,2-bis(N-heterocyclic)ethanes, and methylamines, which is achieved over an ionic liquid (IL, e.g., 1-butyl-3-methylimidazolium tetrafluoroborate, [BMIm][BF4])-Pd/C catalytic system. By simply varying the reaction temperature, formamides and methylamines can be selectively produced, respectively

  用胺和 H2 还原 CO2 通常在不同的催化剂上产生 N-甲酰化或 N-甲基化化合物。在此，我们报道了甲酰胺、1,2-双（N-杂环）乙烷和甲胺的选择性合成，这是在离子液体（IL，例如，1-丁基-3-甲基咪唑鎓四氟硼酸盐，[BMIm][ BF4])-Pd/C 催化体系。通过简单地改变反应温度，可以分别以高产率选择性地生产甲酰胺和甲胺。有趣的是，1,2-双（N-杂环）乙烷也可以通过形成的甲酰胺的 McMurry 反应与随后的氢化反应来获得。发现[BMIm][BF4]可以与甲酰胺反应形成[BMIm]+-甲酰胺加合物；因此与 Pd/C 结合，它可以在 H2 存在下催化甲酰胺的 McMurry 偶联，得到 1，2-双（N-杂环）乙烷。此外，Pd/C-[BMIm][BF4]可以进一步催化1,2-双(N-杂环)乙烷氢解得到甲胺。[BMIm][BF4]-Pd/C 对广泛的底物范围具有耐受性，以中等至高产率提供相应的甲酰胺、1
