  Thiazole and phenoxyacetic acid are key moieties in many natural and synthetic biologically active agents. A series of N-(5-(3,5-methoxyphenyl)-(thiazole-2-yl))phenoxyacetamide derivatives 6an–6bd were designed and synthesized, and their structures were confirmed by NMR and HRMS. Most of derivatives exhibited superior inhibition of Echinochloa crusgalli (E.c.) and Lactuca sativa (L.s.) seed germination

  噻唑和苯氧乙酸是许多天然和合成生物活性剂中的关键部分。设计合成了一系列 N-（5-（3,5-甲氧基苯基）-（噻唑-2-基））苯氧基乙酰胺衍生物 6an–6bd，并通过 NMR 和 HRMS 证实了它们的结构。通过培养皿生物测定，大多数衍生物对 Echinochloa crusgalli （E.c.） 和 Lactuca sativa （L.s.） 种子萌发表现出优异的抑制作用。事实上，除草剂生物测定表明，6an（2-（2,4-二氯苯氧基）-N-（5-（3,5-二甲氧基苯基）-1,3,4-噻二唑-2-基）乙酰胺）对L.s.的抑制作用最好（IC50 = 42.7 g/ha，田间实验为 375 g/ha）。6an 在 2 至 4 倍的田间使用量对 Zea mays 也没有有害影响。此外，转录组学和代谢组学分析显示，6an 显著影响细胞代谢，包括半乳糖代谢以及抗坏血酸和积石酸盐代谢。这些发现突出表明

  A series of [(substituted phenoxyacetoxy)(substituted phenyl)methyl](methyl)phos- phinates containing fluorine were designed and synthesized. All the synthesized compounds were identified by elemental analysis, IR, H-1 NMR, mass spectrometry. O-methyl [(2-fluorophenoxyacetoxy)(2,4-dichlorophenyl)methyl](methyl)phosphinate was further analyzed by X-ray single-crystal diffraction. Their herbicidal activity against a set of weed species was examined. Some of the compounds showed potential herbicidal activity, which provided some indications for further studies on structure modification. Supplemental materials are available for this article.

  On the basis of the previous work for optimization of O,O-diethyl alpha-(substituted phenoxyacetoxy)alkylphosphonates, further extensive synthetic modifications were made to the substituents in alkylphosphonate and phenoxy moieties of the title compounds. New O,O-dimethyl alpha-(substituted phenoxyacetoxy)alkylphosphonates were synthesized as potential inhibitors of pyruvate dehydorogenase complex (PDHc). Their herbicidal activity and efficacy in vitro against PDHc were examined. Some of these compounds exhibited significant herbicidal activity and were demonstrated to be effective inhibitors of PDHc from three different plants. The structure-activity relationships of these compounds including previously reported analogous compounds were studied by examining their herbicidal activities. Both inhibitory potency against PDHc and herbicidal activity of title compounds could be increased greatly by optimizing substituent groups of the title compounds. O,O-Dimethyl alpha-(2,4-dichlorophenoxyacetoxy)ethylphosphonate (I-5), which acted as a competitive inhibitor of PDHc with much higher inhibitory potency against PDHc from Pisum sativum and Phaseolus radiatus than from Oryza sativa , was found to be the most effective compound against broadleaf weeds and showed potential utility as herbicide.
