antioxidants influenced to synthesize some curcumin-related compounds as potential antioxidants. Accordingly, a series of 2,4-diaryl-3-azabicyco[3.3.1]nonan-9-ones were synthesized with polyphenolic and/or polymethoxyphenyl groups by modified Mannich condensations. The yield was significantly improved using BF3·SiO2 as heterogeneous catalyst under mild conditions. Stereochemistry of all the synthesized compounds

the presence of DMAP (0.5 equivalent). The newly prepared compounds were fully characterized by spectral techniques such as FT-IR, 1H NMR, 13C NMR and elemental analysis. Compounds 11-18 were evaluated in vitro as antimicrobial and anti-cancer agents. Compounds 14 and 17 exerted the highest antimicrobial activity among the other tested compounds, showing the maximum action against Bacillus mycoides (27
一系列新的生物活性2,4-二苯基-N- (4-(噻吩-2-基)噻唑-2-基)-3-氮杂双环[3.3.1]壬南-9-亚胺和N- (4- (萘-2-基)噻唑-2-基)-2,4-二苯基-3-氮杂双环[3.3.1]壬南-9-亚胺衍生物11 - 18通过相应的2,4-二苯基-反应合成3-氮杂双环[3.3.1]壬南-9-酮7-10与新合成的2-氨基噻唑3和4。化合物7-10可方便地合成在 DMAP(0.5 当量)存在下,环己酮(1 当量)、苯甲醛衍生物(2 当量)和乙酸铵(1.5 当量)发生环保双曼尼希缩合。新制备的化合物通过FT-IR、1 H NMR、13 C NMR和元素分析等光谱技术进行了充分表征。化合物11-18作为抗菌剂和抗癌剂进行了体外评价。在其他测试化合物中,化合物14和17发挥了最高的抗菌活性,对蕈状芽孢杆菌(分别为 27 和 25 mm)表现出最大的作用。另外,化合物14对蕈状芽孢杆菌的最低抑制浓度
