Ten novel thiazolo[4,5-d]pyrimidines 6a～6j have been synthesized by the reaction of 5-cyano-3-phenyl-2-thioxo-2,3-dihydro-4-ethoxymethylideneaminothiazole (5) with amines via intramolecular cyclization of formamidines. Their structures were characterized by 1H NMR, IR spectra and elemental analysis, and the structure of 6i was further determined by an X-ray single crystal diffraction method. The preliminary bioassay indicated that some compounds showed moderate fungicidal or herbicidal activities.
