Abstract

Novel sixteen enantiopure isoxazolidine-(thio)semicarbazone hybrid derivatives were synthesized by condensation of isoxazolidines based on benzaldehyde derivatives with (thio)semicarbazide in good yield. The analysis of the 1D NMR and NOESY spectra of all compounds unambiguously confirms the E-stereochemistry of the synthesized (thio)semicarbazones.
