  Direct Amination of γ-Halo-β-ketoesters with Anilines

  摘要：

  The direct amination of alpha-haloacetoacetates with anilines is described. Compared to existing methods, this simple protocol provides an attractive strategy to prepare diverse gamma-anilino-beta-ketoesters in one step. Good to excellent yields of the amination products were obtained under robust conditions, providing versatile and useful scaffolds.

• Arylazanylpyrazolone Derivatives as Inhibitors of Mutant Superoxide Dismutase 1 Dependent Protein Aggregation for the Treatment of Amyotrophic Lateral Sclerosis

  The arylsulfanylpyrazolone and aryloxanylpyrazolone scaffolds previously were reported to inhibit Cu/Zn superoxide dismutase 1 dependent protein aggregation and to extend survival in the ALS mouse model. However, further evaluation of these compounds indicated weak pharmacokinetic properties and a relatively low maximum tolerated dose. On the basis of an ADME analysis, a new series of compounds, the arylazanylpyrazolones, has been synthesized, and structure-activity relationships were determined. The SAR results showed that the pyrazolone ring is critical to cellular protection. The NMR, IR, and computational analyses suggest that phenol-type tautomers of the pyrazolone ring are the active pharmacophore with the arylazanylpyrazolone analogues. A comparison of experimental and calculated IR spectra is shown to be a valuable method to identify the predominant tautomer.
