Application of solid support, solvent free reaction condition and a dynamic microwave power system in the chemical synthesis of some novel 1, 3-diaryl-propenones has been described. A series of chalcones(3a-h)were synthesized by the condensation of 4-hydroxy-3,5-dinitroacetophenone with various substituted aromatic aldehydes in presence of montmorrilonite K10 as a catalyst and solid support media under microwave irradiation. The protocol offers several advantages such as simple procedure, fast reaction rate, mild reaction condition, eco-friendly and improved yield as compared to conventional methods. These compounds have been screened for their antibacterial and antifungal activities against different microorganisms. The structures of novel synthesized compounds have been established on the basis of elemental analysis,1H NMR,13C NMR and IR spectral data.
介绍了在化学合成一些新型1,3-二芳基丙酮中,使用固体支持、无溶剂反应条件和动态微波功率系统的应用。在微波辐射下,以蒙脱石K10作为催化剂和固体支持介质,通过4-羟基-3,5-二硝基乙酰苯酮与各种取代芳香醛的缩合反应,合成了一系列查尔酮(3a-h)。该方案具有多种优点,如简单的程序、快速的反应速率、温和的反应条件、环保和比传统方法更高的收率。这些化合物已被筛选用于对抗不同微生物的抗菌和抗真菌活性。新合成化合物的结构已基于元素分析、1H NMR、13C NMR和IR光谱数据确定。
