成功制备了一种环境友好型hpa -树状大分子功能化磁性纳米粒子（Fe3O4@D-NH2-HPA），并首次对其作为一锅法合成高取代吡喃衍生物的新型高效纳米催化剂进行了评价。采用傅里叶变换红外（FT-IR）、粉末x射线衍射（XRD）、热重分析（TGA）、扫描电镜（SEM）和振动样品磁强计（VSM）对纳米磁性催化剂进行了表征。此外，催化剂可以很容易地回收和重复使用，而不会有明显的活性损失。(C) 2018 Elsevier B.V.版权所有
An environmentally friendly HPA-dendrimer functionalized magnetic nanoparticle (Fe3O4@D-NH2-HPA) was successfully prepared and evaluated for the first time as novel and efficient nanocatalyst for the one pot synthesis of highly substituted pyran derivatives. The nano-magnetic catalyst was characterized by Fourier transform infrared (FT-IR), powder X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and vibrating sample magnetometry (VSM). Furthermore, the catalyst can be easily recovered and reused without a significant loss of activity. (C) 2018 Elsevier B.V. All rights reserved.
