Graphical Abstract
  • . Cyclization/isomerization – collective total synthesis of fawcettimine-type alkaloids The bicyclic decahydroquinoline enamide motif can serve as a versatile precursor to access different types of tricyclic N-heterocycles. As demonstrated in the above work from She’s group, the aza-Prins cyclization renders
  • the α-position of enamide to be an active cyclization site, with the alkyne tether acting as the nucleophile. Since it is well-established that alkynes, when activated by transition metals such as gold or platinum, can also function as electrophiles, modulating the reactivity of the decahydroquinoline

  • and six-membered carbocyclic ring system can be achieved in only four steps from a simple acyclic β-keto ester. Keywords: alkaloid; Danheiser annulation; decahydroquinoline; Introduction cis-Fused hydrindanes (bicyclo[4.3.0]nonanes) [1][2], scaffolds of numerous natural products, are amenable to
  • (generated by Me3SiSnBu3 and CsF). As a continuation of our work on the synthesis of Lycopodium alkaloids [23][24][25][26], we hypothesized that decahydroquinoline 1, a versatile building block for the synthesis of phlegmarine-type alkaloids, available in both enantiomeric forms, could also serve as an
  • , following our previously developed procedure, to give decahydroquinoline 1 [23]. The removal of the tert-butyl ester group with TFA, followed by treatment with LiOH in refluxing THF promoted a retro-aza-Michael reaction yielding the ring-opened product 3 [33]. The latter was trapped in situ with benzyl
