An efficiently synthesis of chromones via cyclodehydration of corresponding 1‐(2‐hydroxyphenyl)‐3‐(pyridine‐3‐yl)propane‐1,3‐dione is described under ultrasound irradiation. A series of novel 2‐(pyridine‐3‐yl)‐4H‐chromen‐4‐one derivatives was confirmed on the basis of 1H‐NMR, mass, IR spectral data, and elemental analysis. The synthesized compounds were evaluated for their antibacterial and antifungal
在超声波照射下,描述了通过相应的1-(2-羟基苯基)-3-(吡啶-3-基)丙烷-1,3-二酮的环化脱水有效合成色酮的方法。在1 H-NMR,质量,IR光谱数据和元素分析的基础上,证实了一系列新颖的2-(吡啶-3-基)-4 - H-铬原子-4-酮衍生物。评价合成的化合物的抗菌和抗真菌活性。发现大多数化合物与参考标准药物具有相当的效力。从经济和环境的角度来看,利用超声波辐照,简单的反应条件,分离和纯化使这种操作非常有趣。
