Provided are benzoquinolizidine and indoloquinolizidine derivative compounds prepared by performing Mannich reaction using Azza-Michahael response and DDQ oxidizer from tetrahydroisoquinoline or tryptoline, and to a process for preparing the same. The met
Access to electron-rich arene-fused hexahydroquinolizinones through a gold-catalysis-initiated cascade process
Liu, Lianzhu,Zhang, Liming

Golden Cascade: With a tethered, electron-rich arene as the internal nucleophile, a gold-catalyzed amide cyclization to an alkyne initiates a cascade process that ends with a Ferrier rearrangement. Electron-rich arene-bearing hexahydroquinolizin-2-ones are formed in good yields and can be converted into indole alkaloids in only a few steps. Copyright

Ketalization of 3-acetyl-1,2,6,7,12,12b-hexahydroindolo[2,3-a]quinolizin-2-one (2) with ethylene glycol followed by sodium borohydride reduction and acid hydrolysis gave indolo[2,3-a]quinolizidin-2-one (1) in very high overall yield.
