organophosphorus compounds have been conveniently prepared using 2-(2′-hydroxynapthyl)benzoxazole and 2-(2′-aminophenyl)benzoxazole as starting materials. Phosphorylation and thiophosphorylation was performed using different molar ratio (1:1, 1:2 and 1:3) of phosphorus oxychloride/thiophosphoryl chloride and substituted benzoxazole. The toxicity of newly synthesized phosphorylated/thiophosphorylated compounds
使用 2-(2'-羟基萘基)苯并恶唑和 2-(2'-氨基苯基)苯并恶唑作为原料已经方便地制备了新型有机磷化合物。使用不同摩尔比(1:1、1:2和1:3)的三氯氧磷/硫代磷酰氯和取代苯并恶唑进行磷酸化和硫代磷酸化。在黑曲霉和尖孢镰刀菌上测试了新合成的磷酸化/硫代磷酸化化合物的毒性。所有都被发现抗真菌剂。在 IR、 1 H NMR、 31 P NMR 光谱研究的基础上提出了合理的结构。
Antifungal Activity and Some Novel Organo-Phosphorus Compounds: Preparation and Spectral Characterization
series of N-phosphorylated/ thiophosphorylated compounds on Aspergillus niger and Fusarium oxysporium were examined. The derivatives were obtained in good yield by reacting 2-(2′-aminophenyl)benzoxazole with phosphorous oxychloride and thiophosphoryl chloride in different molar ratios (1:1, 2:1, and 3:1). Structure elucidation of all synthesized compounds was based on the data of elemental analysis,
