heterogeneous catalyst composed of copper nanoparticles supported on montmorillonite K-10 (CuNPs/MK-10) has proven to be highly effective in catalyzing the synthesis of isoxazoles through various one-pot methodologies with high atom economy. These methodologies allow for the use of readily available starting materials, including aldehydes and alkynes through 1,3-dipolar cycloaddition reactions, as well as via
由蒙脱土 K-10 负载的铜纳米颗粒 (CuNPs/MK-10) 组成的易于制备且通用的多相催化剂已被证明在通过各种具有高原子经济性的一锅法方法催化异恶唑的合成方面非常有效。这些方法允许使用容易获得的起始材料,包括通过1,3-偶极环加成反应以及通过炔酮的环异构化得到的醛和炔。此外,CuNPs/MK-10 催化剂通过酰基 Sonogashira 偶联促进了炔酮的原位形成。此外,还开发了一种三步一锅法,从羧酸开始,涉及原位生成酰氯。
