Poly(ethylene glycol) (PEG-400) has been used as sustainable, nonvolatile, and environmental friendly reaction solvent for the synthesis of title compounds. Various diaryl pyrido[3,2-c]coumarins have been synthesized in one step by reacting 4-hydroxy-7-methyl-coumarin with α,β-unsaturated ketones in the presence of ammonium acetate. Further, in vitro antimicrobial (antibacterial and antifungal) activities
聚乙二醇(PEG-400)已用作合成标题化合物的可持续,不挥发且环境友好的反应溶剂。通过一步反应合成了各种二芳基吡啶并[3,2-c]香豆素在存在以下条件下具有α,β-不饱和酮的4-羟基-7-甲基香豆素醋酸铵。此外,针对不同的病原体筛选了化合物的体外抗菌(抗菌和抗真菌)活性。结果表明,它们大多数显示出有效的活性。J.杂环化学。(2010)。
