3a, 5, and 10 with acetic anhydride yielded the acetoxy and N-acetyl derivatives 4, 6, and 11. The mass-spectral fragmentation patterns of nitrogen heterocycles were investigated to elucidate the structure of the prepared compounds. Biological studies of nitrogen heterocycles were carried out to investigate their antimicrobial and anticancer activities; it was found that compounds 5, 10, and 11 were
在甲醇中无水碳酸钾存在下,用硫脲,盐酸胍和硫代氨基脲处理β-芳基-α-氰基丙烯酸乙酯(2a,b),导致形成嘧啶衍生物3和5和硫代氨基脲衍生物9。噻唑衍生物10是通过将硫半脲酮衍生物9与4-甲氧基苯甲酰溴环化而制备的。的乙酰化图3a,5和10用乙酸酐,得到乙酰氧基和Ñ -乙酰基衍生物4,6,和11。研究了氮杂环的质谱碎裂模式,以阐明所制备化合物的结构。对氮杂环进行了生物学研究,以研究其抗微生物和抗癌活性。人们发现,化合物5,10,和11分别为对细菌和真菌具有高活性的化合物,和图3a和3b中也对细菌和真菌的活性。
