这项工作报告了卤代5-(2-羟苯基)吡唑类作为假性泛素类似物,具有靶向磷酸甲基赤藓糖醇(MEP)途径中的酶IspD的潜力。此类类似物是利用伪seedlin核心结构的生物立体置换来设计的,并通过有效的三步法合成。通过基于AtIspD的筛选以及芽前和芽后除草测试,这些化合物被证明具有抗AtIspD(IC50高达3.27μM)和模型植物油菜和n草的相当大的活性,活性中等至优异。在温室试验中,以150 g / ha的速率,三种化合物的除草活性高于假单胞菌素。代表性化合物的分子对接至AtIspD的变构位点揭示了一种类似于假性尿素的结合模式。

Abstract2-Polyfluoroalkylchromones react with aliphatic 1,2-diamines to give 2,3-dihydro-1H-1,4-diazepines. A similar reaction with 1,3-diaminopropane yieldsN,N′-trimethylenebis(2-hydroxyacetophenomines) as a result of scission of the original chromones.

A reaction of chromones with cyanoacetic, acetoacetic, and malonic acid amides in the presence of sodium ethoxide furnished a number of new 3-substituted 6-(2-hydroxyaryl)-2-pyridones in good yields, including those containing a polyfluoroalkyl group at position 4.

Polyhaloalkyl-substituted chromones, γ-pyrones, and β-furanones react with salicylaldehydes in the presence of piperidine to give a wide variety of fused 2H-chromenes in good yields. This novel annulation reaction presumably proceeds by a tandem intermolecular oxa-Michael addition and subsequent intramolecular Mannich condensation.

2-Polyfluoroalkylchromones reacted with diethylenetriamine at similar to20 degreesC to form the corresponding 1,4,8-triazabicyclo[5.3.0]dec-4-ene derivatives. The crystal structures of 5-(2-hydroxyphenyl)-7-trifluoromethyl-1,4,8-triazabicyclo[5.3.0]dec-4-ene and 1-(2-aminoethyl)-7-(2-hydroxy-5-methoxyphenyl)-5-(1,1,2,2-tetrafluoroethyl)-2,3-dihydro-1H-1,4-diazepine were established by X-ray diffraction analysis.

The reaction of 2-hydroxy-2-polyfluoroalkylchroman-4-ones with hydrazine affords 5-hydroxy-3-(2-hydroxyaryl)-5-polyfluoroalkyl-Delta(2)-pyrazolines, whereas 2-polyfluoroalkylchromones under similar conditions produce 3(5)-(2-hydroxyaryl)-5(3)-polyfluoroalkylpyrazoles. 5 - (2-Hydroxyaryl)-1-methyl-3-polyfluoroalkylpyrazoles were synthesized in the reaction with methylhydrazine, and the reaction with phenylhydrazine afforded regioisomeric 3(5)-(2-hydroxyphenyl)-1-phenyl-5(3)-polyfluoroalkylpyrazoles.
