In conclusion, we have reported that four-component Hantzsch condensation reaction can effectively be performed with modified Montmorillonite supported Ni0 nanoparticle catalyst without using any organic solvent. The yield of Hantzsch polyhydroquinoline deriva-tives obtained was up to 95% at room temperature. So, the present pro-cedure provides an efficient and very simple method for the synthesis of polyhydroquinoline derivatives. The advantage of this method is its facile conditions and the product can be isolated very easily with excel-lent purity and that too without the use of column chromatography and the catalyst is recyclable. The simplicity of the present process makes it an interesting alternative to other approaches. The catalyst is expected to contribute to the development of environmentally benign methods and forms a part of the nanomaterial chemistry. The authors are grateful to Dr. P. G. Rao, Director, North East Instituteof Science and Technology (CSIR), Jorhat, Assam, India, for his kind per-mission to publish the work. Dr. P. Sengupta, Head, Materials ScienceDivision is acknowledged for his constant support and encouragement.Thanks are also due to CSIR, New Delhi for the financial support(Network Project NWP 0010 and OLP-3700 Non Network Project). |

總之,我們報(bào)告了用四組分Hantzsch縮合反應(yīng)可以無需使用任何有機(jī)溶劑的條件下有效地用改性蒙脫石支持的Nio納米顆粒催化劑進(jìn)行。在室溫下獲得Hantzsch多聚羥基喹啉衍生物的收益率高達(dá)95%。因此,本方法提供了一種有效而非常簡(jiǎn)單的聚羥基喹啉衍生物的合成方法。這種方法的優(yōu)點(diǎn)是它的條件簡(jiǎn)單和易于分離出純度優(yōu)良的產(chǎn)物,分離過程不需使用柱層析,而且催化劑可以回收(重新利用)。本方法的簡(jiǎn)單性使其成為其他方法的替代方法。預(yù)期催化劑有助于開發(fā)對(duì)環(huán)境無害的方法,并形成納米材料化學(xué)的一部份。 本文作者感謝東北科學(xué)技術(shù)學(xué)院的主任Rao博士(Jorhat, Assam, 印度)的慷慨授權(quán)發(fā)表本工作。材料科學(xué)部主任Sengupta博士的不斷支持和鼓勵(lì)。也感謝新德里CSIR的財(cái)政支持(網(wǎng)絡(luò)項(xiàng)目NWP0010和OLP-3700非網(wǎng)絡(luò)項(xiàng)目)。 |

總之,我們得出,在不使用任何有機(jī)溶劑的前提下,利用改性的蒙脫土支撐的NiO納米粒就可以催化四組份Hantzsch濃縮反應(yīng)。獲得的Hantzsch polyhydroquinoline衍生物產(chǎn)量在室溫下可高達(dá)95%。因此,這為合成Hantzsch polyhydroquinoline衍生物提供了一種有效且簡(jiǎn)便的方法。這種方法的優(yōu)點(diǎn)在于其條件溫合,產(chǎn)品能以高純度分離,且不需要利用柱層析法,還有催化劑可以回收利用。該方法的簡(jiǎn)易使之為成為(行內(nèi)人員)針對(duì)其他方法的一個(gè)很好替代方案。催化劑可以促使環(huán)境友好型生產(chǎn)方案的發(fā)展和成為納米材料化學(xué)的一部分。 作者感謝印度阿薩姆邦州Jorhat市東北科技大學(xué)董事 P. G. Rao博士,因?yàn)樗脑试S,本文才得以發(fā)表; 材料科學(xué)部門主任Sengupta博士,感覺他的不斷支持和鼓勵(lì); 同樣感謝新德里的CSIR的資金支持(網(wǎng)絡(luò)工程項(xiàng)目NWP 0010和非網(wǎng)絡(luò)工程項(xiàng)目OLP-3700)。 |
