摘要：

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