摘  要:
玉嘧磺隆是磺酰脲类除草剂。以乙磺酰基乙腈和1,1,3,3-四甲氧基丙烷为起始原料,经消除加成、取代、环合、硫代、磺酰胺化、缩合六步反应合成得到玉嘧磺隆,总收率(以乙磺酰基乙腈计)38.8%,含量大于98.5%。产物及中间体结构经1HNMR、MS表征,结构正确。

摘  要:
Rimsulfuron is a sulfonylurea herbicide. It was synthesized from 1,1,3,3-tetramethoxypropane and ethylsulfonyl acetonitrile as starting materials, by six steps including elimination-addition, displacement, cyclization, sulfuration, sulfonamination and condensation. The total yield was 38.8%, and the content was above 98.5%. The structures of product and intermediates were comfimed by 1H NMR and MS.
