This invention relates to a novel class of arylsulfonylureidofuro[2,3-d]pyrimidines, such as N'-[(4,6-dimethylfuro[2,3-d]pyrimidin-2-yl)aminocarbonyl]-N,N-dimethylbenz ene-1,2-sulfonamide, and their use as herbicides and plant growth regulants. These novel compounds can be prepared by reacting an appropriate furo[2,3-d]pyrimidin-2-amine with an appropriately substituted arylsulfonyl isocyanate or isothiocyanate.
这项发明涉及一种新型的芳基磺酰脲基呋[2,3-d]嘧啶类化合物,例如N'-[(4,6-二甲基呋[2,3-d]嘧啶-2-基)氨基甲酰]-N,N-二甲基苯-1,2-磺酰胺,以及它们作为除草剂和植物生长调节剂的用途。这些新型化合物可以通过将适当的呋[2,3-d]嘧啶-2-胺与适当取代的芳基磺酰异氰酸酯或异硫氰酸酯反应而制备。
