SYP-3343, (E)-2-(2-((3-(4-chlorophenyl)-1-methyl-1H-pyrazole-5-yloxy)methyl)) phenyl)-3-methoxyacrylate, is a novel fungicide with broad-spectrum and high activity against fungi. In this paper, radioactive pyraoxystrobin, labeled in the pyrazole ring system was achieved from 14C labeled 4-chlorobenzoic acid through substitution, cyclization, and condensation, in an overall chemical and radiochemical yield of 44%. The chemical and radiochemical purity of the title compound was 98.5% and 98.2%, respectively. This labeled SYP-3343 was used as a radiotracer for metabolism, toxicology, mode of action, and other environmental studies. Copyright © 2011 John Wiley & Sons, Ltd.
SYP-3343,(E)-2-(2-((3-(4-氯苯基)-1-甲基-1H-吡唑-5-基氧基)甲基))苯基)-3-甲氧基丙烯酸酯,是一种新型杀真菌剂,具有广谱性和高抗真菌活性。本文以 14C 标记的 4-氯苯甲酸为原料,通过取代、环化和缩合反应,制备出了吡唑环系统中的放射性吡唑醚菌酯,化学收率和放射化学收率合计为 44%。标题化合物的化学纯度和放射化学纯度分别为 98.5% 和 98.2%。这种标记的 SYP-3343 可用作代谢、毒理学、作用模式和其他环境研究的放射性示踪剂。Copyright © 2011 John Wiley & Sons, Ltd.
