  Novel Routes to Enol Ethers, Unsymmetrical Ketones, .alpha.-Bromoalkyl Ketones, 1,4-Diketones, 2-Ethoxy-2-cyclopentenones, and .alpha.-Keto Enamines

  摘要：

  Highly regioselective S(N)2' reactions of adducts 6 (readily prepared by reactions of halides with the allyl anion 12 of 11) with Grignard reagents gave enol ethers 13, which were converted (in one-pot reactions from 11) into ketones 14 and alpha-bromoalkyl ketones 15 in good yields. The monoprotected 1,4-diketone derivative 16 (prepared by Michael addition of the allyl anion 12 with methyl vinyl ketone) was converted both into 1,4-diketones 18 and into protected gamma-hydroxyalkyl ketone 20 by selective Grignard reactions, which could be directed either to the carbonyl, or the protected propenoyl, or to both functionalities. The allyl anion 12 with alpha-substituted acetic esters gave alpha-acylated adducts 24, which underwent in situ unfavored endo-trig cyclization upon treatment with NaH and secondary amines, to give 2-ethoxy-2-cyclopentenones 27 and 28 and alpha-keto enamines 25 in good yield. The mechanism for the cyclization is discussed.

  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.

  The present disclosure relates to bifunctional compounds, which find utility as modulators of Rapidly Accelerated Fibrosarcoma (RAF, such as c-RAF, A-RAF and/or B-RAF; the 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 RAF, 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, or the constitutive activation of the target protein, are treated or prevented with compounds and compositions of the present disclosure.
