series of new ethyl 2‐(ethoxyphosphono)‐1‐cyano‐2‐(substituted tetrazolo[1,5‐a]quinolin‐4‐yl)ethanoate derivatives have been synthesized for the first time of tetrazolo[1,5‐a]quinoline derivatives. Elemental analysis, IR, 1H NMR, 13C NMR, 31P NMR and mass spectral data elucidated the structures of the all newly synthesized compounds. In vitro antimicrobial activities of synthesized compounds have been investigated
一系列新乙基2-(ethoxyphosphono)-1-氰基-2-(取代的四唑并[1,5-一个]喹啉-4-基)乙酸酯衍生物已被用于四唑并首次合成[1,5-一个]喹啉衍生物。元素分析,IR,1 H NMR,13 C NMR,31 P NMR和质谱数据阐明了所有新合成化合物的结构。研究了合成化合物对革兰氏阳性枯草芽孢杆菌,革兰氏阴性大肠杆菌和两种真菌白色念珠菌和黑曲霉的体外抗菌活性。与标准药物相比。这些新合成衍生物的显着微生物学行为具有显着的抗菌和抗真菌活性。

been found as a potential catalyst for an efficient and solvent-free synthesis of symmetrical 2,4,6-triarylpyridines in 86–93% yields. Moreover, catalytic reactivity of bismuth triflate toward tetrazolo[1,5-a]quinoline-4-carbaldehydes for the unexpected formation of their corresponding acetals has been exploited.
三氟甲基磺酸铋已被发现可以有效且无溶剂地合成对称的2,4,6-三芳基吡啶,产率为86-93%。此外,已经开发了三氟甲磺酸铋对四唑并[1,5 - a ]喹啉-4-甲醛的催化反应性,从而意外地形成了它们的相应缩醛。

A series of new alpha-hydroxyphosphonate and alpha-acetoxyphosphonate derivatives have been synthesized for the first time of tetrazolo [1, 5-a] quinoline derivatives. Elemental analysis, IR, H-1 NMR, C-13 NMR and mass spectral data elucidated the structures of the all newly synthesized compounds. In vitro antimicrobial activities of the synthesized compounds were investigated against Gram-positive Bacillus subtilis, Gram-negative Escherichia coli and fungi Candida albicans and Aspergillus niger. Some of the tested compounds showed significant antimicrobial activity. (C) 2009 Elsevier Masson SAS. All rights reserved.

A series of diethyl (4-fluorophenylamino) (substituted tetrazolo[1,5-a]quinolin-4-yl)methyl phosphonate derivatives has been synthesized for the first time from tetrazolo [1,5-a] quinoline derivatives. Elemental analysis, IR, 1H NMR, 13C NMR, and mass spectral data elucidated the structures of the all newly synthesized compounds. In vitro antimicrobial activities of synthesized compounds have been investigated against Gram-positive Bacillus subtilis, Gram-negative Escherichia coli, and two fungi Candida albicans and Aspergillus niger in comparison with standard drugs. Significantly, microbiological behavior of these newly synthesized derivatives possesses significant antibacterial and antifungal activity. Supplemental materials are available for this article.
