Inhoud:
The 1,3-dipolar cycloaddition of unsaturated D-threo-hexaldonolactone 3 and a six-membered cyclic nitrone 11 led to a single adduct 15, which could be transformed into (1S, 2S, 3S, 9aS)-2,3-dihydroxy-1-hydroxymethyl-quinolizidine 28 related to epilupinine via a reaction sequence involving rearrangement of the six-membered lactone ring into a five-membered one, removal of the terminal carbon atom from the sugar chain, cleavage of the N-O bond, and the intramolecular alkylation of the nitrogen atom.
