通过 5 -芳基 -1 ,3 -环己二酮和不同的查尔酮在酸或碱的催化下缩合 ,合成了 7个尚未见文献报道的标题化合物 (3 a～ 3 j)。其结构经元素分析 ,IR和 1H NMR证实并通过化合物 3 a的 13C NMR分析进一步确证
Seven novel title compounds (3 a ~ 3 j) were synthesized by the condensation of 5 - aryl - 1, 3 - cyclohexanedione and different chalcone under acid or base catalysis. Its structure was confirmed by elemental analysis, IR and 1H NMR and further confirmed by 13C NMR analysis of compound 3a
