routes to the naphthoic acid component of kedarcidin chromophore were developed featuring photochemical and thermal electrocyclic ring closure reactions, respectively, as the key step. X-ray crystallographic analysis of the synthetic naphthoic acid confirmed its structure and comparison of 1H and 13C NMR data from its methylamide derivative with those reported for kedarcidin chromophore correspond closely
关键步骤是开发两种不同的合成方法,分别以光化学和热电环闭环反应为酮基西丁生色团的萘甲酸组分。合成萘甲酸的X射线晶体学分析证实了其结构,并比较了其甲酰胺衍生物的1 H和13 C NMR数据与已报道的kedarcidin发色团的数据相吻合,这表明天然产物的这一组分已正确分配。
