efficient synthesis of (−)-swainsonine and (−)-2,8a-di-epi-swainsonine was developed starting from readily available 2-pyridinecarbaldehyde and 3-hydroxypyridine. In particular, it was demonstrated that the mixture of simple indolizidines, i.e. lentiginosine and epi-lentiginosine, being readily available by a number of different synthetic routes, can be directly converted to swainsonine.
从容易获得的2-吡啶甲醛和3-羟基吡啶开始开发了一种有效合成(-)-swainsonine和(-)-2,8a-di- epi -swainsonine的方法。特别地,已经证明,可以通过许多不同的合成途径容易获得的简单的吲哚嗪核苷的混合物,即龙胆草碱和表-龙胆草碱,可以直接转化成猪wa碱。
