series of novel 1,2,4-triazolo[1,5-a]pyrimidine derivatives, α-(5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine-2-thio)acetamides 3 and α-(5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine-2-sul-fonyl)acetamides 4, have been designed and synthesized by a three-step synthetic route. The structures of all compounds prepared were confirmed by elemental analyses and by 1H NMR and mass spectroscopy. The results of
为了发现具有高除草活性和低毒性的新化合物,一系列新的1,2,4-三唑并[1,5-a]嘧啶衍生物,α-(5,7-二甲基-1,2,4 -三唑并[1,5-a]嘧啶-2-硫代)乙酰胺3和α-(5,7-二甲基-1,2,4-三唑并[1,5-a]嘧啶-2-磺酰基)乙酰胺4、已设计合成三步合成路线。所制备的所有化合物的结构均通过元素分析、1H NMR 和质谱确认。初步生物测定结果表明标题化合物对油菜 (Brassica campestris L.) 和稗草 (Echinochloca crusgalli L.) 具有良好的除草活性 © 2001 John Wiley & Sons, Inc.
