acid-mediated 5/6-endo-dig reductive hydroamination cascade of enynyl amines. The brevity of the developed strategy allowed for the collective stereoselective total synthesis of various alkaloids, including (±)-pyrrolidine cis-225H, (±)-epi-197B, (±)-epi-225C, the family of (+)-solenopsins and (+)-isosolenopsins, and the formal synthesis of (±)-bgugaine and (+)-azimic acid.
带有疏水链的吡咯烷和哌啶的立体选择性合成已经通过烯炔胺的无金属、路易斯酸介导的5/6-内位还原氢胺化级联实现。所开发策略的简洁性允许集体立体选择性全合成各种生物碱,包括(±)-吡咯烷顺式-225H、(±)- epi -197B、(±)- epi -225C、(+)-家族Solenopins 和 (+)-isosolenopsins,以及 (±)-bgugaine 和 (+)-azimic Acid 的正式合成。
