Photoelectron Angular Distribution Study of Some Isoxazoles Combined with Perturbation Theoretic Approach

Photoelectron spectra of isoxazole, 5-methylisoxazole, and 3,5-dimethylisoxazole were studied by the technique of photoelectron angular distribution measurements combined with a first order perturbation theoretic approach.Photoelectron spectra of oxazole, 4-methyloxazole, furan, and 2-methylfuran, which are closely related to isoxazole, were also discussed at the same time for the sake of comparison.The first three bands of the isoxazoles were assigned to the ?, ?, and n bands from the top, respectively, while those of the oxazoles were identified as the ?, n, and ? bands from the top.

Selective access to dipyrazolo-fused pyridines: Via formal [3 + 2 + 1] heteroannulation of methyl ketones with pyrazol-5-amines

A fascinating new form of the Hantzsch reaction with methyl ketones and pyrazol-5-amines for the selective synthesis of dipyrazolo-fused pyridines has been discovered. This special [3 + 2 + 1] heteroannulation was accomplished via the domino generation of two C-C bonds and one C-N bond. Preliminary mechanistic studies indicated that the I2/DMSO system realized the oxidative carbonylation of Csp3-H of methyl ketones, while Cu(OTf)2 acted as a relay reagent to accelerate this transformation.

65. Herstellung von substituierten 2-Aminooxazol-4-carbonitrilen.

During our synthetic programme to convert 4-isoxazolylthioureas 3 into the corresponding carbodiimides 5, a side reaction leading to the hitherto unknown 2-aminooxazole-4-carbonitriles 6 was observed.By selecting appropriate reaction conditions, it was possible to improve the yields of the carbodiimides 5 as well as of the novel oxazole-carbonitriles 6 at will, thus allowing the synthesis of 6 to be conducted in very good yields.To overcome the difficulty of isolating unstable carbodiimides, the synthesis of 6 is best carried out in a one-pot procedure.A limited mechanistics study showed that the formation of 6 proceeds via 5 as the only intermediate.The stability of the N=C=N bonds against base attack (depending strongly on both sterical hindrance and electronic-density factors) forms the only limitation of this new synthetic pathway to oxazole-4-carbonitriles.

Herbicidal activity and molecular docking study of novel accase inhibitors

Acetyl-CoA carboxylase (ACCase) is an important target enzyme for the development of new bleaching herbicides. On the basis of structure-activity relationships and active subunit combinations, a series of novel 2-phenyl-3-cyclohexanedione enol ester derivatives was designed and synthesized by coupling and acylation reactions. The preliminary biological tests indicated good post-emergent herbicidal activity at a dosage of 150?300 g ai/ha, superior to that of clethodim against barnyard grass. Compound 3d was safe with respect to maize, even at a dosage of 300 g ai/ha. Compound 3d showed the best ACCase inhibitory activity in vitro, with a value of 0.061 nmol h-1 mg-1 protein, superior to that of clethodim. Molecular docking modeling showed that compound 3d and clethodim had the same interactions with surrounding residues, leading to an excellent combination with the active pocket of ACCase. That may have been the mechanism responsible for the death of the barnyard grass. The present work suggests compound 3d as a potential lead structure for further development of novel ACCase inhibitors.

An isoxazole-accelerated nitro oxidation type fluorescent detection and imaging for hydrogen sulfide in cells

Hydrogen sulfide (H2S) emerges as an important mediator of human physiology and pathology but remains difficult to study, so it is urgent to find a sensor with high selectivety and rapidly response to detect H2S. The detection mechanism of H2S is various, and the reduction of nitro has developed rapidly in recent years. However, the reported nitro-based H2S probes still have drawback such as slow response. In this work, we introduced isoxazole to strengthen the oxidizability of nitro group, resulted in the response time significantly reduced within 55 s. In addition, this probe could be used to detect and imaging exogenous/endogenous H2S in HepG-2 cells.
