  Synthesis and Herbicidal Activity of 3-Aryl-5-(haloalkyl)-4-isoxazolecarboxamides and Their Derivatives

  摘要：

  A series of unique 3-aryl-5-(haloalkyl)-4-isoxazolecarboxamides have been prepared which exhibit, in both greenhouse and field studies, significant preemergent and postemergent herbicidal activity in the grams per hectare range against broadleaf and narrowleaf weeds. The key step in the formation of the fully substituted isoxazole ring 2 is 1,3 dipolar cycloaddition of a haloalkyl-substituted acetylenic ester and a nitrile oxide intermediate. The 3-aryl-5-(halo alkyl)-4-isoxazolecarboxylate esters 2 are converted to isoxazole-4-carboxamide herbicides 5 and 6, secondary amides 7, and amino acid derivatives 8. Greatest activity was observed with compounds having a combination of three substituents: a substituted phenyl ring in the 3-position, a primary or secondary carboxamide in the 4-position, and a difluorochloromethyl group in the, 5-position of the isoxazole ring.

  A compound represented by the formula (I) 1 wherein one of R 1 and R 2 is a hydrogen atom or a substituent and the other is an optionally substituted cyclic group; W is a bond or a divalent aliphatic hydrocarbon group; Y is a group of the formula: —OR 3 (wherein R 3 is a hydrogen atom, an optionally substituted hydrocarbon group, an optionally substituted heterocyclic group or an optionally substituted acyl group) or an optionally esterified or amidated carboxyl group, or a salt thereof or a prodrug thereof has a superior insulin secretion promoting action and a hypoglycemic action and shows low toxicity. Therefore, the compound is useful as a pharmaceutical agent, particularly as an agent for the prophylaxis or treatment of diabetes and diabetic complications, and the like.

  Polysubstituted phenylisoxazoles were designed and synthesized to discover new antibacterial agents via [3 + 2] cycloaddition. Thirty-five compounds with a phenylisoxazole scaffold were characterized by NMR, HRMS, and X-ray techniques. After being evaluated against Xanthomonas oryzae (Xoo), Pseudomonas syringae (Psa), and Xanthomonas axonopodis (Xac), 4-nitro-3-phenylisoxazole derivatives were found

  设计并合成了多取代的苯基异恶唑，以通过[3 + 2] 环加成发现新的抗菌剂。通过 NMR、HRMS 和 X 射线技术对 35 种具有苯基异恶唑支架的化合物进行了表征。在针对米黄单胞菌( Xoo )、丁香假单胞菌( Psa ) 和轴突黄单胞菌( Xac )进行评估后，发现 4-硝基-3-苯基异恶唑衍生物具有更好的抗菌活性。进一步的研究表明，这些化合物的 EC 50值远优于阳性对照双汞噻唑。
