摘要: Ten novel thiazolo[4,5-d]pyrimidines 6a similar to 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 (1)H 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.
