The 1-phenyl-1,5-dihydro-3-methylthio(methylsulfonyl)-5-aryl-6-(4-ethyloxycarbonylmethoxyphenyloxy)-pyrazolo[3,4-d]pyrimidin-4-ones (6 and 7) have been synthesized bya novel tandem aza-Wittig and annulation reactions of iminophosphorance 4 with aromatic isocyanate and substituted phenols. The structures of all newcompounds were confirmed by elemental analyses, 1H NMR, IR and MS spectroscopies. The results of preliminary bioassay indicate that compounds 6and 7 possess high herbicidal activity against the root of rape and barnyard grass.

Key words: pyrazolo[3,4-d]pyrimidin-4-one, phenoxyl acetic acid ethyl ester, aza-Wittig reaction, synthesis, herbicide
