The stereoselective synthesis of oxazolidine derivatives was accomplished,starting from ephedrine,pseudo-ephedrine and substituted benzaldehyde.Seven kinds of new substituted phenyl-3,4-dimethyl-5 phenyloxazolidine were first reported.At the same time,the stereochemical structures and the spectral characteristics were studied for these oxazolidines.
A new Schiff base ligand,2-hydroxy-1-naphthylaldchyde guanyl hydrazone(HL) and its copper(Ⅱ) complexes are synthesized in ethanol.Their structures are characterized by elemental analysis,molar conductivity,UV spectra,IR spectra,fluorescence spectra and electrochemical property.The results show that the complexes have rings with M-O、M-N and M-NH bonds.
