Hexachlorocylotriphosphazene (1) was reacted with 4-hydroxy-3-methoxybenzaldehyde to give hexakis[(4-formyl-2-methoxy)phenoxy]cyclotriphosphazene (2). Hexakis[(4-(hydroxyimino)2-methoxy)phenoxy]cyclotriphosphazene (3) was synthesized by reaction of 2 with hydroxlamine hydrochloride in pyridine. Compound 3 was reacted with benzyl chloride, acetyl chloride, allyl bromide, benzoyl chloride, propanoyl chloride, 4-methoxybenzoyl chloride, 2-chlorobenzoyl chloride, chloroacetyl chloride, methyl iodide, and thiophene-2-carbonyl chloride. From these reactions, full or partially substituted compounds were obtained, usually in high yields. Pure or defined products could not be obtained from reaction of 3 with methacryloyl chloride and O-acetylsalicyloyl chloride. The structures of the compounds were determined by elemental analysis, and IR, 1H, 13C, and 31P NMR spectroscopy. The synthesized compounds were screened for in-vitro antimicrobial activity against two Gram-positive bacteria (Staphylococcus aureus and Enterococcus faecalis), two gram-negative bacteria (Escherichia coli and Klebsiella pneumonia), and fungal strains (Aspergillus niger, and Candida albicans) by the agar well diffusion method. Few compounds had significant activity against both Gram-positive and Gram-negative bacteria. None of the compounds had antifungal activity except compounds 7 and 9, which had moderate activity.
Hexachlorocylotriphosphazene (1) 与 4-hydroxy-3-methoxybenzaldehyde 反应生成 hexakis[(4-formyl-2-methoxy)phenoxy]cyclotriphosphazene (2)。通过 2 与盐酸羟胺在吡啶中的反应,合成了六[(4-(羟基亚氨基)2-甲氧基)苯氧基]环三磷嗪(3)。化合物 3 与苄基氯、乙酰氯、烯丙基溴、苯甲酰氯、丙酰氯、4-甲氧基苯甲酰氯、2-氯苯甲酰氯、氯乙酰氯、甲基碘和噻吩-2-甲酰氯反应。从这些反应中可以得到完全或部分取代的化合物,通常产量很高。从 3 与甲基丙烯酰氯和 O-乙酰基水杨酰氯的反应中无法得到纯净或确定的产物。这些化合物的结构是通过元素分析、红外光谱、1H 光谱、13C 光谱和 31P NMR 光谱确定的。采用琼脂井扩散法筛选了合成化合物对两种革兰氏阳性菌(金黄色葡萄球菌和粪肠球菌)、两种革兰氏阴性菌(大肠埃希菌和肺炎克雷伯菌)以及真菌菌株(黑曲霉和白色念珠菌)的体外抗菌活性。少数化合物对革兰氏阳性菌和革兰氏阴性菌都有明显的活性。除了化合物 7 和 9 具有中等程度的活性外,其他化合物都不具有抗真菌活性。
