Abstract

We have successfully developed a new Mo-Al2O3/p-TSA organocatalyst which has improved the yield of the Mannich reaction. This protocol has the advantage of mild conditions, high yield, easy work-up, environmentally friendly procedure, and the solid catalyst was recycled. The catalyst was analysed by XRD, SEM, and EDS techniques. The synthesized Mo-Al2O3composites were used in the presence of p-toluene sulfonic acid (p-TSA) conducts the one-pot three-component Mannich reaction and various β-amino ketones prepared with good yields and characterized by IR, 1H, and 13C NMR Techniques.

一种多相、高效、可重复使用的Mo-Al2O3复合材料基有机催化剂用于一锅三组分Mannich反应合成β-氨基羰基化合物

我们成功地开发了一种新的Mo-Al2O3/p-TSA有机催化剂，它提高了曼尼奇反应的产率。该方案具有条件温和、产率高、易于后处理、工艺环保、固体催化剂可回收利用等优点。通过XRD、SEM和EDS等技术对催化剂进行了分析。合成的Mo-Al2O3复合材料在对甲苯磺酸（p-TSA）存在下进行一锅三组分Mannich反应，制备了产率高的各种β-氨基酮，并用IR、1H和13C NMR技术对其进行了表征。

期刊介绍： Orbital: The Electronic Journal of Chemistry is a quarterly scientific journal published by the Institute of Chemistry of the Universidade Federal de Mato Grosso do Sul, Brazil. Original contributions (in English) are welcome, which focus on all areas of Chemistry and their interfaces with Pharmacy, Biology, and Physics. Neither authors nor readers have to pay fees. The journal has an editorial team of scientists drawn from regions throughout Brazil and world, ensuring high standards for the texts published. The following categories are available for contributions: 1. Full papers 2. Reviews 3. Papers on Education 4. History of Chemistry 5. Short communications 6. Technical notes 7. Letters to the Editor The Orbital journal also publishes a number of special issues in addition to the regular ones. The central objectives of Orbital are threefold: (i) to provide the general scientific community (at regional, Brazilian, and worldwide levels) with a formal channel for the communication and dissemination of the Chemistry-related literature output by publishing original papers based on solid research and by reporting contributions which further knowledge in the field; (ii) to provide the community with open, free access to the full content of the journal, and (iii) to constitute a valuable channel for the dissemination of Chemistry-related investigations.
