| Synthesis of Sulfonylurea Herbicide Rimsulfron |
| TAN Xiao-jun WANG Dang-sheng（School of Chemistry and Chemical Engineering; Jinan University; Jinan 250022; China） |
| Abstract：Rimsulfron ,a kind of effective agricultural and horticultural herbicides, was synthesized by a five-step reaction from 1,1,3,3-tetramethoxypropane malonaldehyde bis(dimethyl acetal) and ethylsulfonyl acetonitrile as starting materials . The structure of rimsulfron and mind intermediates were comfimed by ~(1)HNMR. |
| Key words：sulfonylureas herbicides; rimsulfron; synthesis |
