摘　　要：A series of new thiazoline derivatives 2-alkyl（aryl） imino-4-amino-5-ethoxycarbonyl-3-phenyl-3H- thiazoline （3） and bis（2-imino-4-amino-5-ethoxycarbonyl-3-phenyl-3H-thiazoline alkylene （4） have been synthesized by reactions of intermediate 4-amino-5-ethoxycarbonyl-2-methylthio-3-phenyl-3H- thiazolinium sulphate （2） with alkylamines or arylamine in 64%-89% yields. The structures of 3 and 4 have been confirmed by 1H NMR, El-MS, IR spectroscopy and elemental analyses. Some compounds exhibited high or moderate herbicidal activities against the roots of rapeseed and barnyard grass at 100 mg/L.A series of new thiazoline derivatives 2-alkyl（aryl） imino-4-amino-5-ethoxycarbonyl-3-phenyl-3H- thiazoline （3） and bis（2-imino-4-amino-5-ethoxycarbonyl-3-phenyl-3H-thiazoline alkylene （4） have been synthesized by reactions of intermediate 4-amino-5-ethoxycarbonyl-2-methylthio-3-phenyl-3H- thiazolinium sulphate （2） with alkylamines or arylamine in 64%-89% yields.
