By X-ray analysis of demissidine hydroiodide the stereochemistry of the indolizidine skeleton of the solanidanes has been determined. Thus all the natural solanidane alkaloids demissidine, solanidine, leptinidine, rubijervine, isorubijervine, and veralobine are proven to posses (22R:NS)-configuration, whereas the so-called 22-iso-solanidanes have (22S:NS)-configuration. According to chemical transformations
通过X-射线分析氢碘伏司他尼,已确定茄苷的吲哚并立定骨架的立体化学。因此,证明了所有天然的茄尼烷生物碱去甲上腺苷,茄尼丁,瘦素啶,茜草藤,异丁烯藤和维拉罗宾具有(22R:NS)-构型,而所谓的22-异-茄胺类具有(22S:NS)-构型。根据化学转化,还给出了在C-22处的已知立体异构体22,26-亚氨基-胆甾烷的绝对构型:例如四氢索拉索定A分别具有(22S)-和二氢番茄碱B(22R)-构型。
