A stereospecific synthesis of solanidine has been accomplished by a sequence in which the key step is Michael addition of methyl 5-nitro-2S-methyl pentanoate to cis-5,17(20)-pregnadien-3β-ol-20-one. The adduct is elaborated to a hexacyclic amide which on reduction affords the desired alkaloid.
通过顺序完成了茄碱的立体有择合成,其中关键步骤是将5-硝基-2S-戊酸甲酯的迈克尔加成到顺式-5,17(20)-孕烯-3β-ol-20-one上。将加合物精制为六环酰胺,还原后可提供所需的生物碱。
