from the key intermediate 2 previously used for the preparation of derivatives with a normal yohimbane skeleton, the synthesis of rac-deserpidine (1b) and the rac-raunescine epimer 9c, having an epi-allo and allo skeleton, respectively, has been performed. In the course of the synthesis several stereoisomers of C-18-substituted allo-yohimbine have been prepared and characterized by spectroscopic and
从先前用于制备具有正常育亨宾骨架的衍生物的关键中间体2开始,合成了rac- deserpidine(1b)和rac- raunescine Epimer 9c,它们分别具有Epi-allo和allo骨架。 。在合成多个立体异构体的过程中C-18取代的同种育亨宾已经制备和表征通过光谱和化学方法。
