Total syntheses of indoloquinolizidine alkaloid (+/-)-, R-(+)-, and S-(-)-deplancheine are described here. The synthesis features an enantioselective intramolecular formal aza-[3 + 3] cycloaddition for the construction of the quinolizidine CD-ring. This application serves to introduce a new synthetic strategy for the synthesis of indoloquinolizidine alkaloids.
本文描述了吲哚喹嗪生物碱(±)-、R-(+)-和S-(-)-去普兰琴的全合成。该合成的特点是通过对映选择性分子内形式氮杂-[3 + 3]环加成反应来构建喹嗪环的CD环。此应用为吲哚喹嗪生物碱的合成引入了一种新的合成策略。
