| Abstract: | 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 by a novel tandem aza-Wittig and annulation reactions of iminophosphorance 4 with aromatic isocyanate and substituted phenols. The structures of all new compounds were confirmed by elemental analyses, 1H NMR, IR and MS spectroscopies. The results of preliminary bioassay indicate that compounds 6 and 7 possess high herbicidal activity against the root of rape and barnyard grass. |
