A selective deconstructive strategy of indolo[2,3-a]quinolizines to hexahydroindolizin-3-ones under transition-metal-free conditions was developed and applied to the total synthesis of both enantiomers of cuscutamine. Additionally, controversy of the absolute configuration of the natural products was clarified.
开发了一种在无过渡金属条件下将吲哚[2,3- a ]喹啉选择性解构为六氢吲哚嗪-3-酮的策略,并将其应用于菟丝子胺两种对映异构体的全合成。此外,澄清了天然产物绝对构型的争议。
