A highly practical total synthesis of (-)-kainic acid has been accomplished. The synthesis features the stereoselective alkylation of an iodolactone intermediate efficiently prepared from (+)-carvone and introduction of carboxylic acid by hydrolysis of a nitrile accompanied by epimerization. kainoids - iodolactone - Curtius rearrangement - stereoselective alkylation - total synthesis
(-)-海藻酸的高度实用的全合成已经完成。该合成的特征在于由(+)-香芹酮有效制备的碘内酯中间体的立体选择性烷基化,以及通过腈水解伴随差向异构化而引入羧酸。 类胡萝卜素-碘内酯-库尔修斯重排-立体选择性烷基化-全合成
