  摘要：

  通过将希夫碱配体扇区和纤维素纳米纤维吊带锚定在MNP（Fe 3 O 4 ）上，制备了新型可回收钴三核磁性催化剂，并将其命名为MNP@CNF@ATSM–Co( II )。另外，MNP 和 CNF 具有令人非常感兴趣的吸附特性。这样，该催化剂被设计用于在无溶剂条件下合成哌啶衍生物以及以EtOH为溶剂进行醇氧化反应。值得注意的是，该催化剂对环境安全，不需要外部碱。这种MNPs@CNF@ATSM–Co( II )可分离催化剂已经使用各种表征技术进行了评估，例如FT-IR、XRD、FE-SEM、EDX、EDS、ICP、TGA、DLS、HRTEM和VSM。该催化剂与多种苯甲醇、苯甲醛和胺衍生物相容，并产生了所有这些都引起足够兴趣的互补偶联产物。证明了Co（三核）在催化剂中的协同性能，并分别合成了MNPs、MNPs@CNF、MNPs@CNF@ATS–Co( II )和MNPs@CNF@ATSM–Co( II

• Thiourea dioxide promoted efficient organocatalytic one-pot synthesis of a library of novel heterocyclic compounds

  DOI：10.1039/c1ob05818e

  日期：——

  The utility of thiourea dioxide as an efficient organocatalyst for the library synthesis of novel heterocyclic compoundsvia one-pot multicomponent coupling reactions is disclosed. Thiourea dioxide is an inexpensive and readily accessible catalyst, resulting in better product yields as compared to the corresponding thiourea as catalyst. Thiourea dioxide is found to be insoluble in various organic solvents and therefore at the end of the reaction products can be separated by extraction with diethyl ether and the recovered catalyst can be used several times with consistent catalytic activity.

  介绍了二氧化硫脲作为高效有机催化剂在一锅多组分偶联反应中合成新型杂环化合物的应用。与相应的硫脲催化剂相比，二氧化硫脲作为一种廉价且易于获得的催化剂，能带来更好的产物收率。二氧化硫脲在多种有机溶剂中难以溶解，因此反应结束后，产物可通过乙醚萃取分离，且回收的催化剂能多次重复使用，保持稳定的催化活性。

  A mild and efficient method for the synthesis of polysubstituted tetrahydropyridines has been developed which involves a three-component reaction of an arylamine (2 equiv.), an araldehyde (2 equiv.) and ethyl (or methyl) acetoacetate (1 equiv.) in MeCN under ambient conditions, in the presence of yttrium nitrate, Y(NO₃)₃·4H₂O. This appears to be the first time yttrium nitrate has been used as a catalyst for this type of synthesis of tetrahydropyridines.
