order to find novel pyrimidinyl carboxylic acid analogs with high activity and low toxicity, a series of novel pyrimidinyl derivatives containing an α-amino phosphonate moiety 5 was synthesized by the condensation of 4-(4,6-dimethoxypyrimidin-2-yloxy)phenoxyacetic 3a or propionic acids 3b with dialkyl α-amino substitutedbenzyl phosphonates 4. Their structures were characterized by spectroscopic data (IR
为了寻找具有高活性和低毒性的新型嘧啶基羧酸类似物,通过4-(4,6-二甲氧基嘧啶-2-基氧基)苯氧基乙酸缩合合成了一系列含有α-氨基膦酸酯部分5的新型嘧啶基衍生物。 3a 或丙酸 3b 与二烷基 α-氨基取代苄基膦酸酯 4。它们的结构通过光谱数据(IR、1H NMR、31P NMR、MS)和元素分析表征。初步除草活性(体外)的结果表明,这些化合物中的大多数对双子叶杂草(Brassica campestris L)表现出比单子叶杂草(Echinochloa crus-galli)更高的除草活性。进一步的生物测定(体内)表明,某些化合物 5 对苋菜(A. retroflexus)在芽后处理中。补充材料可用于本文。转至出版商在线版的磷、硫和硅及相关元素,查看免费的补充文件。
