We investigated the radical addition of 4-hydroxycoumarin (1a) and 4-hydroxyquinoline (1b) with conjugated dienes (2a-f) mediated by cerium(IV) ammonium nitrate (CAN) resulting in ethenyl substituted 2,3-dihydrofurocoumarin (3a-f) and 3,5-dihydrofuroquinoline (3g, 3h) compounds in moderate to good yields. All compounds were characterized by spectroscopic methods (IR, MS, and $^1}$H and $^13}$C NMR) and microanalysis. Antifungal activities of these compounds were investigated against the fungi Candida albicans, C. parapsilosis, C. krusei, C. glabrata, C. tropicalis, and Aspergillus fumigatus.
我们研究了由铈(IV)铵硝酸盐(CAN)介导的4-羟基香豆素(1a)和4-羟基喹啉(1b)与共轭二烯(2a-f)之间的自由基加成反应,生成了乙烯基取代的2,3-二氢呋喃香豆素(3a-f)和3,5-二氢呋喃喹啉(3g, 3h)化合物,产率中等到良好。所有化合物均通过光谱方法(红外光谱,质谱,$^1}$H和$^13}$C NMR)和微量分析进行了表征。这些化合物的抗真菌活性针对的真菌包括白色念珠菌、假丝酵母、克鲁斯酵母、光滑念珠菌、热带念珠菌和烟曲霉进行了研究。
