The omega-iodo-alpha,beta-alkynoates and their ketone, sulfone or phosphonate analogues react with delta-chloropropylamines in MeCN assisted with K2CO3 to undergo a sequential S(N)2/Michael addition/S(N)2/S(N)2 reaction process, giving polysubstituted indolizidines or quinolizidines in good to excellent yields. This sequential reaction process is also compatible with three other substituted alpha,beta-alkynoates, affording quinolizidine analogues in moderate to good yields. (c) 2006 Elsevier Ltd.

β-Enaminoesters bicycliques: Synthese et reduction stereospecifiques. Acces a l'isoretronecanol, la trachelanthamidine, la lupinine et l'epilupinine
precursors of nitrogen-bridged bicyclic β-enaminoesters . The compounds are prepared either by intramolecular alkylation of β-enaminoesters or by thermolysis of β-enaminoesters . A stereospecific reduction of compounds under thermal control leads to bicyclic β-aminoesters , , or which are good precursors of natural aminoalcohols like lupinine or isoretronecanol .
