ABSTRACT:
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.
