“…Therefore, this review will summarize the synthetic approaches to the tricyclic aminoketones 1 since 1963, including highlight the construction of the C‐/D‐/E‐ring with the all‐carbon quaternary stereogenic center, and subsequent give a brief introduction to complete the synthesis of aspidosperma and kopsia alkaloids. In addition, this review will discuss the formation of tricyclic aminoketones 1 based on their precursors, including tricyclic lactams, [10–23] tricyclic vinylogous amides, [24–28] tricyclic enones, [29–31] tricyclic ethers, [32] tricyclic ketals, [33] tricyclic esters, [34] and non‐tricyclic precursors [35–38] …”
