ZJ0273, propyl 4-(2-(4,6-dimethoxypyrimidin-2-yloxy)benzylamino)benzoate, is a broad-spectrum herbicidal ingredient used for weed control in oilseed rape in China. Two mono-labeled ZJ0273, propyl 4-(2-(4,6-dimethoxypyrimidin-2-yloxy)[phenyl-3,4,5,6-3H4]benzylamino)benzoate (7) and propyl 4-(2-(4,6-dimethoxy[4,6-14C2]pyrimidin-2-yloxy)benzylamino)benzoate (12), were synthesized separately from [2,3,4,5,6-3H5]phenol in a four-step yield of 27% and from 4,6-dichloro-2-(methylthio)[4,6-14C2]pyrimidine in a three-step yield of 54%. In addition, two dual-labeled analogues of ZJ0273 were prepared by homogeneously mixing tritium-labeled ZJ0273 (7) in the benzyl ring separately with two carbon-14-labeled ZJ0273 (2, 12) in the benzoate ring and the pyrimidine ring. These labeled ZJ0273 could be used as radiotracers in the studies on the metabolism, mode of action, environmental behavior, and fate of ZJ0273. Copyright © 2008 John Wiley & Sons, Ltd.
ZJ0273 是 4-(2-(4,6-二甲氧基嘧啶-2-基氧基)苄基氨基)苯甲酸丙酯,是一种广谱除草剂,在中国用于油菜除草。两种单标 ZJ0273,即 4-(2-(4,6-二甲氧基嘧啶-2-基氧基)[苯基-3,4,5,6-3H4]苄基氨基)苯甲酸丙酯(7)和 4-(2-(4,6-二甲氧基[4,6-14C2]嘧啶-2-基氧基)苄基氨基)苯甲酸丙酯(12)、分别由[2,3,4,5,6-3H5]苯酚和 4,6-二氯-2-(甲硫基)[4,6-14C2]嘧啶合成,前者的四步合成收率为 27%,后者的三步合成收率为 54%。此外,通过将苄基环上的氚标记 ZJ0273(7)与苯甲酸环和嘧啶环上的两个碳 14 标记 ZJ0273(2,12)分别均匀混合,制备出了两种双标记的 ZJ0273 类似物。这些标记的 ZJ0273 可用作放射性示踪剂,用于研究 ZJ0273 的代谢、作用方式、环境行为和归宿。Copyright © 2008 John Wiley & Sons, Ltd.
