Several piperazine bis(benzoxaboroles) have been obtained both in solution as well as in the solid state. The environmentally friendly mechanochemical approach – hitherto not applied for the preparation of benzoxaboroles – was particularly beneficial in the case of two products afforded in low yields in solution. The in vitro studies showed high potential of the studied bis(fluorobenzoxaboroles) as
已经在溶液和固态中获得了几种哌嗪双(苯并恶硼烷)。环境友好的机械化学方法——迄今为止尚未用于制备苯并恶硼烷——在溶液中以低产率提供两种产品的情况下特别有益。体外研究表明,所研究的双(氟苯并氧杂硼杂环)作为抗真菌剂具有很高的潜力,同时也突出了氟取代基位置对其微生物活性的影响。对A. niger , A. terreus , P. ochrochloron , C. tenuis和C. albicans的活性最高由已知的苯并氧杂硼酸抗真菌药物 Kerydin® (Tavaborole) 的类似物展示。

The straightforward synthesis of a highly biologically active 3-piperazine-bisbenzoxaborole and its fluorine analog has been described. The obtained bisbenzoxaboroles have been used in the synthesis of their phenylboronic acidsanalogs. One diboronic acid has been also isolated as hydrochloride salt as well as its methyl monoester. All the described compounds display unique molecular architectures
