摘要

利用氨基磺酸功能化 Zr-MOF-NH2 作为活性酸性金属有机框架催化剂，通过 2-羟基-5-(芳基二氮基)苯甲醛、4-氨基古柯碱和 6-氨基-1,3-二甲基脲嘧啶或 6-氨基脲嘧啶在 EtOH 中的一步反应，在回流条件下合成了新的 6-氨基-5-(4-氨基-2-氧代-2H-Chromen) (AAOC) 类似物。通过采用不同类型的光谱技术，如 XRD、BET、FESEM、EDS、FT-IR 和 TGA，对得到的 UiO-66-NHSO3H 进行了表征。此外，该方法还具有操作简便、反应时间短、催化剂可回收且催化活性不会发生太大变化等优点。

Sulfamic Acid Supported Zr-MOF: An Effective Catalyst for One-Step Synthesis of Novel 6-Amino-5-(4-Amino-2-Oxo-2H-Chromen) Analogs

Sulfamic acid-functionalized Zr-MOF-NH₂ was used as an active acidic metal-organic framework catalyst for the synthesis of new 6-amino-5-(4-amino-2-oxo-2H-chromen) (AAOC) analogs via a one-step reaction between 2-hydroxy-5-(aryldiazenyl)benzaldehyde, 4-aminocumarin, and 6-amino-1,3-dimethyluracil or 6-amino-uracil in EtOH under reflux conditions. The resulting UiO-66-NHSO₃H was characterized by employing different types of spectroscopic techniques such as XRD, BET, FESEM, EDS, FT-IR, and TGA. In addition, ease of procedure, short reaction time, and recycling of the catalyst without much change in the catalytic activity are the advantages of this method.
