A series of β-amino carbonyl compounds containing coumarin (4a–h) and benzofuran (6a–i) moieties was synthesized by a three component Mannich reaction of 3-acetyl-2H-chromen-2-one (1) or 1-(1-benzofuran-2-yl) ethanone (5) with p-substituted aromatic aldehydes (2a–g) and aromatic amines (3a–b) in the presence of cerric ammonium nitrate as a catalyst. The newly synthesized compounds were screened for
通过3-乙酰基2 H-铬2-2-酮(1)或1-的三组分曼尼希反应合成了一系列包含香豆素(4a – h)和苯并呋喃(6a – i)部分的β-氨基羰基化合物。(1-苯并呋喃-2-基)乙酮(5)与对取代的芳族醛(2a – g)和芳族胺(3a – b)在硝酸铈铵作为催化剂的情况下。筛选了新合成的化合物的抗微生物和抗氧化活性。化合物4b,4e,4f,6f,6g和6i表现出对微生物的抑制作用,最小抑制浓度范围为0.040至0.500 mg / mL,化合物4b,4c,6c,6e和6i表现出有希望的自由基清除活性,化合物4b,4f,6c,6d,和6h显示出与Fe 2+离子的良好螯合能力。研究了合成的化合物对接在酶上,即氨基葡萄糖6-磷酸合酶,以预测受体活性位点的结合亲和力和方向。
