The total synthesis of the indole alkaloid (−)-andranginine has been achieved in 10 steps. Key reactions of the synthesis include a nucleophilic addition of acetylenyl anion to chiral N-sulfinyl imine, an intramolecular N-alkylation reaction to close the C ring, and a dienyne metathesis cascade reaction to construct the DE rings. Meanwhile, 16-epi-(−)-andranginine was also obtained with the developed
吲哚生物碱(−)-andranginine的全合成经过10步完成。合成的关键反应包括乙炔阴离子与手性N-亚磺酰亚胺的亲核加成、分子内N-烷基化反应以闭合C环,以及二烯炔复分解级联反应以构建DE环。同时,利用所开发的策略还获得了16- epi -(−)-andranginine。
