  使用 Fe25Ru75@SILP 催化剂对苯乙酮衍生物进行选择性加氢脱氧：一种合成烷基酚和苯胺的实用方法

  摘要：

  基于广泛的羟基-、氨基-和硝基-苯乙酮衍生物作为容易获得的底物的选择性加氢脱氧，开发了一种生产有价值的烷基酚和苯胺的通用合成途径。固定在咪唑基负载型离子液相 (Fe 25 Ru 75 @SILP) 上的双金属铁钌纳米粒子可作为高活性和选择性催化剂，用于侧链脱氧而不会使芳环氢化。该催化系统允许在连续流动条件下运行，具有高稳定性和灵活性，如 3',5'-二甲氧基-4'-羟基苯乙酮和 4'-羟基壬苯酮作为模型底物的交替转化所证明的那样。

  A versatile synthesis of the suitably functionalized pyrrolo[2,1-f][1,2,4]triazine nucleus is described. SAR at the C-5 and C-6 positions of the 4-(3-hydroxy-4-methylphenylamino)pyrrolo[2,1-f][1,2,4]triazine template led to compounds with good in vitro potency against VEGFR-2 kinase. Glucuronidation of the phenol group is mitigated by incorporation of a basic amino group on the C-6 side chain of the
