A new class of spirooxindole compounds were synthesized by the 1,3-dipolar cycloaddition reaction of 2-arylmethylidene-benzimidazo[2,1-b]thiazol-3-one with azomethine ylide (generated in situ by the reaction of isatin with sarcosine). The structures of the products were characterized thoroughly by IR, MS, NMR techniques, and elemental analysis together with X-ray crystallographic analysis. The results of crystal dif-fraction indicated that this 1,3-dipolar cycloaddition proceeded with well both high stereoselectivity and regioselectivity.

Key words: crystal structure, cycloaddition, azomethine ylide, spirooxindole
