|Title:||A stereoselective entry to tetrasubstituted quinolizidines and the puzzling structural assignment of the lupin alkaloid plumerinine|
|Abstract:||A thermodynamically controlled stereoselective synthesis of quinolizidinone (+/-)-13 via alpha-amidoalkylation of an intermediate N-acyliminium ion derived from a-ethoxy piperidine 9, followed by intramolecular Michael addition is described. Based on their NMR data, quinolizidine alcohols 14 and 15 were ruled out as possible structures of the lupin alkaloid plumerinine.|
