The [2-formyl-4-(trifluoromethyl)phenyl]boronic acid as well as its benzoxaborole and bis(benzoxaborole) derivatives were obtained and their properties studied. The 2-formyl compound displays an unusual structure in the crystalline state, with a significant twist of the boronic group, whereas in DMSO solution it tautomerizes with formation of a cyclic isomer. All the studied compounds exhibit relatively
得到了[2-甲酰基-4-(三氟甲基)苯基]硼酸及其苯并氧杂环戊二烯和双(苯并氧杂环戊二烯)衍生物,并对其性质进行了研究。2-甲酰基化合物在结晶状态下表现出不寻常的结构,具有明显扭曲的硼基团,而在 DMSO 溶液中它会发生互变异构,形成环状异构体。所有研究的化合物都表现出相对较高的酸度以及合理的抗菌活性。对接研究显示所有研究化合物与白色念珠菌LeuRS 结合袋的相互作用。对蜡状芽孢杆菌的高活性测定了 2-甲酰基化合物以及新型双(苯并氧杂硼酸),而研究的苯并氧杂环戊烯显示出高抗真菌作用,对白色念珠菌和黑曲霉 的 MIC 值分别等于 7.8和 3.9 μg/mL 。所研究的化合物都没有表现出对大肠杆菌的合理活性。
