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 .
