Synthesis and Biological Activity of Ethyl 4-Alkyl-2-(2-(substituted phenoxy)acetamido)thiazole-5-carboxylate

(Chemical Equation Presented) A series of novel ethyl 4-(methyl or trifluoromethyl)-2-(2-(substituted phenoxy)acetamido)thiazole-5-carboxylates 7a, 7b, 7c, 7d, 7e and 8f, 8g, 8h, 8i, 8j, 8k, 8l, 8m, 8n, 8o, 8p, 8q, 8r were synthesized, and their structures were confirmed by IR, 1H-NMR, MS spectra and elemental analysis. The results of preliminary bioassays show that some of the title compounds exhibit moderate to good herbicidal activities. Compared with the fluorine free compounds 7a, 7b, and 7e, the compounds bearing fluorine 8g, 8j, and 8q showed higher herbicidal activities with 70-100% inhibition against Capsella bursa-pastoris, Amaranthus restroflexus, and Eclipta prostrata at the dosage of 150 g/ha, which indicated that the trifluoromethyl on the thiazole ring was beneficial for the herbicidal activity. Furthermore, compounds 8f, 8g, 8h, 8i, 8j, 8k, 8l, 8m, 8n, 8o, 8p, 8q, 8r were tested for fungicidal activity against Pseudoperonospora cubensis at 500 μg/mL. Compounds 8f and 8q showed the best fungicidal activity with more than 80% inhibition.

Synthesis and biological activity of 1-(Substituted phenoxyacetoxy)- 1-(pyridin-2-yl or thien-2-yl)methylphosphonates

A series of novel O,O-dimethyl 1-(substituted phenoxyacetoxy)-1-(pyridin-2-yl or thien-2-yl)methylphosphonates 6a-n and 7a-d were synthesized. Their structures were confirmed by IR, 1H NMR, mass spectroscopy, and elemental analyses. The results of preliminary bioassays show that some of the title compounds exhibit moderate to good herbicidal and fungicidal activities. For example, the title compounds 6a, 6c, 6l, 6m, and 7d possess 90-100% inhibition against most of the tested plants at the dosage of 1500 g ai/ha, whereas the title compounds 6b, 6g-h and 6n possess 92-100% inhibition against Fusarium oxysporum, Phyricularia grisea, Botrytis cinereapers, Gibberella zeae, Sclerotinia sclerotiorum, and Cercospora beticola at the concentration of 50mg/L.

Finding new elicitors that induce resistance in rice to the white-backed planthopper Sogatella furcifera

Herein we report a new way to identify chemical elicitors that induce resistance in rice to herbivores. Using this method, by quantifying the induction of chemicals for GUS activity in a specific screening system that we established previously, 5 candidate elicitors were selected from the 29 designed and synthesized phenoxyalkanoic acid derivatives. Bioassays confirmed that these candidate elicitors could induce plant defense and then repel feeding of white-backed planthopper Sogatella furcifera.

Synthesis and herbicidal activity of [(Substituted Phenoxyacetoxy) (Substituted Phenyl)Methyl](Methyl) phosphinates containing fluorine

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, 1H 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.

Synthesis and herbicidal activity of 2-(substituted phenoxyacetoxy)alkyl-5, 5-dimethyl-1,3,2-dioxaphosphinan-2-one containing fluorine

A series of novel 2-(substituted phenoxyacetoxy)alkyl-5,5-dimethyl-1,3,2- dioxaphosphinan-2-one bearing fluorine 5a-n and fluorine free 5o-q were designed and synthesized. The results of bioassay showed that some of the target compounds exhibited excellent herbicidal activities to Abutilon theophrasti, Brassica juncea, Amaranthus retroflexus and Eclipta prostrata in post-emergence treatment at a dosage of 150 g ai/ha. It could be found that the type and position of fluorine-containing group as X or Y on benzene ring had a very important effect on herbicidal activity. Compound 5l 2-[(2-chloro-4- fluorophenoxy)acetoxy](methyl)methyl-5,5-dimethyl-1,3,2-dioxaphosphinan-2-one showed notable herbicidal activity, with 100% inhibition against A. theophrasti and A. retroflexus; and compound 5m 2-(3-trifluoromethylphenoxyacetoxy)(methyl) methyl-5,5-dimethyl-1,3,2-dioxaphosphinan-2-one with 100% inhibition against A. theophrasti even at a dosage of 75 g ai/ha. Additional crop selectivity testing showed that compounds 5g 2-(3-trifluoromethylphenoxyacetoxy)(phenyl)methyl-5,5- dimethyl-1,3,2-dioxaphosphinan-2-one and 5l are safe to rice, corn, cotton, rape and wheat.

Synthesis and anti-inflammatory activity of 2-aryloxy methyl oxazolines

A series of potential biologically active 2-aryloxy methyl oxazolines 3a-n have been synthesized from substituted hydroxybenzenes 1a-n with good chemical yield. The compounds 3a-n were screened for their anti-inflammatory, ulcerogenic, cyclooxygenase activities and also for their acute toxicity. The potency of the compounds was compared with that of the standard drugs, aspirin and phenyl butazone. The outcome indicates that compounds 3b (48.2%), 3h (48.5%) and 3l (46.5%) offered significant anti-inflammatory activity with low ulcerogenic activity than the standard drugs.

Skeletal Rearrangements Preceding CO Loss from Metastable Phenoxymethylene Ions Derived from Phenoxyacetic Acid and Anisole

The loss of CHO2(.) from the molecular ion of phenoxyacetic acid and the expulsion of an H(.) atom from ionized anisole lead to phenoxymethylene ions, which fragment predominantly by CO loss on the microsecond time-scale.Carbon-13 labelling reveals that ca. 90percent of the CO molecules expelled from the metastable ions derived from phenoxyacetic acid incorporate the carbon atom from the 1-position of the phenyl group of the parent compound, whereas the residual CO molecules contain one of the other carbon atoms of the aromatic ring.The 2-fluoro- and 2-methylphenoxymethylene ions derived from the appropriate aryloxyacetic acids behave similarly, i.e. the carbon atom of the methylene group of the parent compound is not incorporated in the expelled CO molecules.In contrast, ca. 45percent of the CO molecules eliminated from the metastable phenoxymethylene ions formed from ionized anisole contain the carbon atom of the methyl group, while the remaining part contains the carbon atom from the 1-position of the phenyl ring of the parent compound.This result is taken as evidence for the occurrence of a skeletal rearrangement of the anisole molecular ion leading to an interchange between the carbon atom of the methyl group and the carbon atom at the 1-position of the ring.The elimination of CO from the metastable ions generated from either phenoxyacetic acid or anisole gives rise to a composite metastable peak.Conclusive evidence as to the formation of (+) isomers other than the phenoxymethylene ion is not obtained, indicating that the composite metastable peak is a result of two competing reactions both leading to CO loss.Possible mechanisms of these reactions are discussed together with the mechanism of the skeletal rearrangement of the molecular ion of anisole prior to H(.) loss.
