reacted with ethyl acetoacetate in alcohol to yield corresponding pyrazole-6-methoxybenzothiazole (A4). Moreover, the compound (A2) was reacted with 4- substituted aromatic aldehydes in absolute ethanol to create Hydrazones (A5a-d). Synthesized compounds were investigated as anti-bacterial activity against five microorganisms:(Gram-positive: Bacillus subtilis & Staphylococcus aurea). (Gram-negative: Pseudomonas
当前的工作报告了对6-甲氧基-2-氨基苯并噻唑(A1)的合成和生物学评估,该合成是通过对氨基苯甲酸与硫氰酸铵反应,然后将所得硫脲与催化量的溴进行氧化闭环而制得的,在碱性介质中。所得化合物(A1)与各种醛进行缩合反应,生成Hy(A3a-d)。在浓HCl和乙二醇溶液存在下,通过化合物(A1)与99.9%水合肼的反应,制得6-甲氧基2-肼基苯并噻唑(A2)。之后,使化合物(A2)与乙酰乙酸乙酯在醇中反应,得到相应的吡唑-6-甲氧基苯并噻唑(A4)。而且,使化合物(A2)与4-取代的芳族醛在无水乙醇中反应,生成Hy(A5a-d)。研究了合成的化合物对五种微生物的抗菌活性:(革兰氏阳性:枯草芽孢杆菌和金黄色葡萄球菌)。(革兰氏阴性:铜绿假单胞菌和肠杆菌)
