Condensation of ethylenediamine with 2-phenyl-1,2,3-triazole-4-carboxaldehyde (1) or quinoxa-line-2-carboxaldehyde (2) gave bis-Schiff base 3 or 4, which then reacted with α-chloro-oximes to afford bis- bis-4,5-dihydro-1,2,4-oxadiazoline derivatives 6a～6f or 7a～7f by 1,3-dipolar cycloaddition. The structures of new compounds were confirmed by elemental analysis, IR, 1H NMR and MS spectra.

Key words: bis-Schiff base, 1,3-dipolar cycloaddition, 2-phenyl-1,2,3-triazole-4-carboxaldehyde, bis-4,5-dihydro-1,2,4-oxadiazoline derivative, qinoxaline-2-carboxaldehyhyde
