A new class of methylene-bis-4,6-diarylbenzo[d]isoxazoles was synthesized by the reaction of methylene-bis-aryl-6-hydroxymethylene-2-cyclohexenone with hydroxylamine hydrochloride, followed by aromatization with DDQ. Chemical structures of the newly synthesized compounds were elucidated by their IR, 1H NMR, 13C NMR, MS, and elemental analyses. Furthermore, all the compounds were screened for their
一类新的亚甲基-双-4,6-二芳基苯并[ d ]异恶唑 通过亚甲基-双-芳基-6-羟基亚甲基-2-环己烯酮的反应合成 用盐酸羟胺,然后用DDQ进行芳构化。通过IR,1 H NMR,13 C NMR,MS和元素分析阐明了新合成化合物的化学结构。此外,对所有化合物针对各种真菌的抗真菌活性进行了筛选,并与它们的单体化合物进行了比较。在合成的化合物中,, , 和 被认为是对最活跃的白色念珠菌(ATCC 10231),烟曲霉(HIC 6094),毛癣菌(IFO 9185)和须癣毛癣菌(IFO 40996)。有趣的是,这些化合物, , 和 在3.12μg/ mL的浓度下对白念珠菌的杀菌活性低于标准两性霉素BJ Heterocyclic Chem。,46,497(2009)的浓度。
