噻吩磺隆

噻吩磺隆用途

噻磺隆属内吸传导型苗后选择性除草剂，是支链氨基酸合成抑制剂，能抑制缬氨酸、亮氨酸、异亮氨酸的生物合成，阻止细胞分裂，使敏感作物停止生长。主要用于防除禾谷类作物小麦、大麦、燕麦、玉米田间的阔叶杂草，如反枝苋、马齿苋、播娘蒿、荠菜、猪毛菜、猪殃殃、婆婆纳、牛繁缕等，对刺儿菜、田旋花及禾草等无效。小麦、大麦2叶期到孕穗前，杂草出齐至2～4叶期，用75%干悬剂0.25～0.41g/100m²，对水4.5kg，加入液量0.2%的非离子表面活性剂，茎叶喷雾处理。

3-氨基-2-羧甲基噻吩的制备丙烯腈在DMF存在下，于10～12℃通氯反应6～7h，得2，3-二氯丙腈；巯基乙酸在浓硫酸存在下，与无水甲醇于室温下反应8h，得巯基乙酸甲酯。
将巯基乙酸甲酯、无水甲醇和甲醇钠冷至10～15℃，滴加二氯丙腈和无水甲醇溶液，滴毕于10～15℃继续反应5h，减压蒸出甲醇，残余物冷却后加入冰水，过滤，产品收率55%，m.p. 58～61℃。
2-羟甲基-3-磺酰氯噻吩的制备将冰醋酸及少许盐酸在泠却下通入二氧化硫，置冰浴中待用。
将3-氨基-2-羧甲基噻吩于0～5℃加入到盐酸、冰醋酸混合液中，搅拌，将亚硝酸钠水溶液慢慢滴入，继续反应30min，于0℃将待用的二氧化硫溶液加入，再加少许氯化亚铜，控制温度自然升至25～30℃，反应10h，将反应液倒入冰水中，过滤、洗涤、干燥，收率75.7%，m.p.66～68℃。
2-羧甲基-3-磺酰氨基噻吩的制备以二氯乙烷为溶剂，将所得的磺酰氯噻吩溶解，冷却至5℃，通入氨气。氨解产物过滤，滤液浓缩处理得产品，收率95%，m.p. 110～114℃。
