activities against two Gram-positive (Staphylococcus aureus and Bacillus subtilis) and two Gram-negative bacteria (Escherichia coli and Proteus vulgaris), and also two fungal agents (Aspergillus niger and Candida albicans). Most of the compounds were found to exert potentantibacterial action with broad-spectrum antibacterial activity. Likewise, few compounds were revealed to have potent antifungal properties
我们描述了卤代芳基和杂环标记的2,3-二氢-1 H-茚满一酮衍生物的成功合成,以及它们的抗菌和抗真菌特性。通过研磨,搅拌和超声辐照方法合成了来自2,3-二氢-1 H-茚基-1-一的总共15种衍生物。这些发现表明,超声技术在时间和合成性能方面越来越令人满意。测试了合成的化合物对两种革兰氏阳性菌(金黄色葡萄球菌和枯草芽孢杆菌)和两种革兰氏阴性菌(大肠杆菌和寻常变形杆菌)以及两种真菌剂的抗菌活性。黑曲霉和白色念珠菌)。发现大多数化合物都具有强大的抗菌作用,并具有广谱抗菌活性。同样,几乎没有化合物显示出对黑曲霉和白色念珠菌具有有效的抗真菌特性。通过FT-IR,1 H NMR,13 C NMR和HRMS光谱技术对合成的化合物进行表征。 图形摘要
Highly Diastereoselective One-Pot Synthesis of Spiro{cyclopenta[<i>a</i>]indene-2,2‘-indene}diones from 1-Indanones and Aromatic Aldehydes
has been studied using DFT methods at the B3LYP/6-31G* level. The dimerization takes place through a process involving a Michaeladdition of a carbanion, obtained by deprotonation of 5g at the 3-position, to a second molecule of 5g, followed by an intramolecular Michaeladdition in the corresponding intermediate. The final protonation of the resulting anion accounts for the formation of the cis-fused
