A special, efficient and reusable heterogeneous catalytic system is reported for the one‐pot three‐component synthesis of a series of malonamide and 2,3,4,5‐tetrahydrobenzo[b][1,4]oxazepine derivatives in the presence of a heterogeneous material composed of MCM‐48/H5PW10V2O40 in aqueous media and at room temperature. The products were identified using physical data (melting points) by comparison with
报道了一种特殊,有效且可重复使用的非均相催化体系,用于在存在a的情况下一系列丙二酰胺和2,3,4,5-四氢苯并[ b ] [1,4]氧杂a庚因衍
生物的单锅三组分合成。在
水性介质中和室温下,由MC
M-48 / H 5 PW 10 V 2 O 40组成的非均质材料。通过与文献中报道的那些进行比较,使用物理数据(熔点)来鉴定产物。同样,通过红外,1 H NMR,13 C NMR和CHN分析来表征新化合物的结构。版权所有©2016 John Wiley&Sons,Ltd.
