Transannular reductive rearrangement of bridged cyclic α-amino ketones led to the aza-tricyclic frameworks azepinoindole, hydrolulolidine, and hydrojulolidine of the typical alkaloids of Stemona, Aspidosperma, and Lycopodium, respectively. This facile approach demonstrates the potential applicability of the Clemmensen–Clemo–Prelog–Leonard reductive rearrangement of tricyclic α-amino ketones for the
桥环环状α-氨基酮的跨环还原重排分别导致了典型的Stemona,Aspersperma和Lycopodium生物碱的氮杂-三环构架氮杂吲哚,氢氟尿苷和氢氟尿烷。这种简便的方法证明了Clemmensen-Clemo-Prelog-Leonard三环α-氨基酮的还原重排在氮杂杂环合成中的潜在适用性。
