One-potthree-componentsynthesis of novel macrocyclic imidazolidines has been accomplished in good yields via a facile [3+2] cycloaddition reaction of azomethine ylide, derived from paraformaldehyde and sarcosine, with various macrocyclic imines as dipolarophiles. The effect of solvent on the [3+2]-dipolar cycloaddition reaction is also studied.

were synthesized. All ligands and their related complexes were characterized by elemental analysis, IR spectroscopy, in the case of ligands 1H, 13C NMR and EI-Mass and for [Cu2L2′](NO3)2 and [NiL1(CH3CN)2(CH3OH)2](ClO4)2 complexes X-ray crystal structure determination have been performed. Crystal structure showed 1D zigzag polymer for [Cu2L 1′2 ](NO3)2 and macrocyclic structure for [NiL1(CH3CN)2(CH3OH)2](ClO4)2
