antifungal activities. Direct fluorination using diethylaminosulfur trifluoride as a nucleophilic fluorinating reagent was carried out in the present paper. Undoubtedly this methodology gives a facile and straightforward pathway to construct 1-(1,3-diphenyl-1H-pyrazol-4-yl)-3,3-difluoro-1,3-dihydro-indol-2-ones in good yields. The structure of new fluorinated 1-(1,3-diphenyl-1H-pyrazol-4-yl)-3,3-difluoro-1
通过吲哚-2的反应已实现了1-(1,3-二苯基-1 H-吡唑-4-基)-3,3-二氟-1,3-二氢吲哚-2-酮的战略合成。,3-二酮(异丁二烯)和取代的溴乙酰苯,然后环化反应,并评价其体外抗菌和抗真菌活性。本文采用三氟化二乙氨基硫作为亲核氟化剂进行直接氟化。无疑,这种方法为构建1-(1,3-diphenyl-1 H -pyrazol-4-yl)-3,3-difluoro-1,3-dihydro-indol-2-ones高产提供了简便而直接的途径。。基于1 H表征了新的氟化1-(1,3-二苯基-1 H-吡唑-4-基)-3,3-二氟-1,3-二氢-吲哚-2-酮的结构,13 C和19 F核磁共振波谱和质谱数据。通过核Overhauser效应光谱确认目标化合物的结构。一些合成的化合物对细菌和真菌显示出良好的抗菌活性。
