reported the first four members of heteroarotinoids, the names of which are ethyl (E)-p-[2-(4,4-dimethylthiochroman-6-yl)propenyl]benzoate (1b), ethyl (E)-p-[2-(4,4-dimethylchroman-6-yl)propenyl]benzoate (1c), ethyl (E)-p-[2-(4,4-dimethyl-1-oxothiochroman-6-yl)propenyl]benzoate (1d), and (E)-p-[2-(4,4-dimethylchroman-6-yl)propenyl]benzoic acid (1e). IR, 1H NMR and 13C NMR data have been recorded for each
据报道,杂芳烃类化合物的前四个成员,其名称为(E)-对-[2-(4,4-二甲基硫代苯并吡喃-6-基)丙烯基]苯甲酸乙酯(1b),(E)-对-乙基[2-(4,4-二甲基苯并吡喃-6-基)丙烯基]苯甲酸酯(1c),(E)-对-[2-(4,4-二甲基-1-氧代硫代苯并吡喃-6-基)丙烯基]苯甲酸乙酯( 1d)和(E)-对-[2-(4,4-二甲基苯并吡喃-6-基)丙烯基]苯甲酸(1e)。每种化合物的IR,1H NMR和13C NMR数据均已记录,并支持结构指定。为了为将来类似物的比较提供坚实的基础,对(E)-对-[2-(4,4-二甲基硫代苯并吡喃-6-基)丙烯基]苯甲酸乙酯(1b)的单晶进行了X射线分析)和前体4,4-二甲基硫代苯并六基甲基甲酮1,1-二氧化物(18)。这些关于杂芳烃类化合物1b的数据表明,存在于晶胞中的两个分子的每一个中,两个芳基环系几乎垂直(分别为86.37度和84.17度)。
