in turn prepared from (–)-galanthamine via(–)-epigalanthamine. The relative stereochemistry of the pair of epimeric, allylic alcohols derived from Pummerer's ketone has been determined. The conversion of these alcohols into allylic chlorides with thionyl chloride and with trisdimethylaminophosphine and carbon tetrachloride is described. Biosynthetic conversion of tritiated galanthamine and narwedine
已通过NO-二甲基化确定了酚类芳基科的生物碱chlidanthine的结构,得到(-)-加兰他敏甲硫醇,然后由(-)-加兰他敏经(-)-表没食子胺制得。已经确定了源自Pummerer酮的一对差向异构烯丙基醇的相对立体化学。描述了将这些醇与亚硫酰氯以及与三二甲基氨基膦和四氯化碳转化为烯丙基氯化物。Ch草中已观察到ti化的加兰他敏和那屈丁的生物合成转化为桔黄素。
