  Ruthenium catalyzed reactions of ethylene glycol with primary amines: steric factors and selectivity control

  摘要：

  The selectivity of reactions of ethylene glycol with primary amines in the presence of RuCl2(PPh3)3 at 120-degrees-C is highly dependent on the steric nature of the amine. Selectivity to di-amination is favored by smaller alkyl groups on the amine while large amines cleanly yield ethanolamines. This contrasts with the results obtained with secondary amines at this temperature, in which ruthenium-triphenylphosphine catalyst systems always favor mono-amination. In the case of sec-butyl amine, where almost equal amounts of mono- and di-aminated product are obtained, the selectivity can be shifted to mono-amination by the addition of excess triphenylphosphine. The steric effects seen in these reactions are consistent with standard steric parameters available from the literature.

  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.
