A new class of thiazolo[3,2-a]pyrimidine compounds were synthesized by the reaction of 5-carbethoxyl-4-aryl-6-methyl-1,2,3,4-tetrahydropyrimidin-2-ones with dimethyl acetylenedicarboxylate. The reaction has the advantages of excellent yields and simple workup procedures. The products were char-acterized thoroughly by IR and NMR (1H, 13C, COSY, HSQC and HMBC) together with elemental analysis. The X-ray crystallographic analysis of the 1,3-dipolar cycloaddition derivative of the title product provided the direct information for the structure of the product.

Key words: dimethyl acetylenedicarboxylate, cycloaddition, crystal structure, thiazolo[3,2-a]pyrimidine
