Abstract

The chiral N-D-ribosylnitrones 5-10 have been synthesized in four steps respectively, in the fourth step, D-ribosyloxime (4) condensed with substituted benzaldehyde in cool condition. The heterocyclization of Z- nitrone 6 with substituted N-arylmaleimide by 1,3-dipolar cycloaddition were afforded new heterocyclic system of isoxazolidine derivatives 11-16 and 11'-16' as a mixture of diastereoisomers, the new isoxazolidines 11-16 have been separated purely and characterized by H NMR, mass spectra and elemental analysis.
