Synthesis of Fluorine-Containing Derivatives of 5-Arylisoxazoles and 4,5-Dichlorothiazole

Alkylation of fluorophenols and phenolic aldehydes with 5-phenyl(p-tolyl)-3-chloromethylisoxazole under the Williamson reaction conditions afforded the corresponding ethers. Condensation of the resulting phenolic aldehyde derivatives and 5-phenyl(p-tolyl)isoxazole-3-carbaldehydes with p-fluoroaniline resulted in fluorine-containing azomethines. Acylation of fluorinated amines with 5-(p-tolyl)isoxazole- and 4,5- dichloroisothiazole-3-carbonyl chlorides gave rise to fluorinated amides bearing isoxazole and isothiazole fragments, representatives of which showed a synergistic effect in compositions with insecticides.

DABCO-catalyzed sp(3) C-H activation: rapid access to isoxazole or coumarin-fused 3-quaternary carbon oxindoles and isoxazole-fused pyrrolidinones

A facile and efficient methodology was developed for the synthesis of isoxazole or coumarin-fused 3-quaternary carbon oxindoles and isoxazole-fused pyrrolidinones via DABCO-catalyzed sp(3) C-H activation of 5-methyl-isoxazole or 4-methylcoumarin. Furthermore, the biological activity of the isoxazole or coumarin-fused 3-quaternary carbon oxindoles 3 and 5 has been preliminarily demonstrated by in vitro evaluation against human prostate cancer cells PC-3 and human leukemia cells 1(562 by the MIT-based assays using the commercially available standard drug Cisplatin as a positive control. These results suggested that most of the compounds 3 and 5 showed considerable cytotoxicities to these two cell lines 1(562 and PC-3, and a methyl or an ethyl group of acrylates and an oxindole moiety located in the isoxazole-fused 3-quaternary carbon oxindoles 3 are beneficial for the activity. In addition, the activity of all the afforded isoxazole-fused pyrrolidinones 7 were also evaluated against Gram-positive bacteria Staphylococcus aureus (MTCC96) and Gram-negative bacteria Escherichia coli (ATCC25835) using Penicillin as a standard drug for Gram-positive organism or Streptomycin as standard drug for Gram-negative organism. The results demonstrated that most of the compounds 7 had comparable in vitro inhibitory activity against Gram-positive bacteria Staphylococcus aureus (MTCC96) with the positive control Penicillin. The results also indicated that isoxazole-fused pyrrolidinone analogs had significantly better inhibition ability against Gram-positive bacteria Staphylococcus aureus (MTCC96) than against Gram-negative bacteria Escherichia coli (ATCC25835).

Theoretical investigation of gold(I)-catalyzed intramolecular SEAr in isoxazole derivatives: Mechanisms, origin of regioselectivity, and role of hydrogen acceptor

A detailed theoretical study on the mechanism and regioselectivity of the Au(I)-catalyzed intramolecular electrophilic aromatic substitution (SEAr) in 4-substituted isoxazole derivatives is reported, using two model substrates, 4-(1-methylpropargyloxy)isoxazole (Series A) and 4-(1-methyl propargylamino)isoxazole (Series B). The obtained theoretical data reveal similar energy profiles in both series for the 6 endo dig heteroatom-assisted SEAr to form an alkenyl Au(I) intermediate. Then, in the series A, the 1,3-H-shift assisted by the 4-propargyloxyisoxazole leads to a final product and the catalyst regeneration. In contrast, in the series B, the elimination of proton by N-phenylbenzaldimine additive results in an iminium cation and dihydropyridine. In the next step, a hydride from dihydropyridine is accepted by the iminium cation to furnish pyridinium and N-benzylidenebenzenaminium species. Subsequently, protodeauration leads to a final product and N-phenylbenzylamine along with the catalyst regeneration. In the absence of N-phenylbenzaldimine additive, 4-(1-methylpropargylamino) isoxazole accepts the hydride instead of N-phenylbenzylamine and causes the consumption of the reactants, thus accounting for a low product yield. Furthermore, the regioselectivity and its origin as well as the rationalization of the deuterium labeling experiments are also examined and discussed in detail.

4-(4-Methoxyphenyl)-3-methyl-1,6-dioxa-2,8-diaza-s-indacen-5(7H)-one

In the molecule of the title compound, C16H12N2O4, the pyridine ring is oriented at the same dihedral angle of 2.92 (3)degrees with respect to the furan and isoxazole rings, while the dihedral angle between furan and isoxazole rings is 1.34 (3)degrees. The dihedral angle between the benzene and pyridine rings is 53.23 (3)degrees. In the crystal structure, intermolecular C-H center dot center dot center dot O interactions link the molecules into chains. Weak pi-pi contacts between isoxazole and benzene rings [centroid-centroid distance = 3.969 (3) angstrom] may further stabilize the structure.

Synthesis, pharmacological evaluation and molecular docking studies of indanone derivatives

A new series of isoxazole fused indanones were synthesized form indane-1,3-dione. The newly synthesized derivatives were confirmed by IR, H-1 NMR, and mass spectral data. The synthesized title compounds were evaluated for analgesic, anti-inflammatory, and antimicrobial activities. The modifications carried out in indanone had a positive effect in anti-inflammatory activity when compared to that of other pharmacological activities. The compounds BD (6) , BD (7) , BD (9) , BD (10) , and BD (11) showed good anti-inflammatory activity when compared to that of standard indomethacin. BD (3) , BD (4) , and BD (5) compounds possess moderate anti-inflammatory activity. Some compounds possess moderate analgesic and antimicrobial activity. Docking study reveals that isoxazole nucleus is essential for biological activity. It was concluded that the fusion of isoxazole with indanone nucleus will increase anti-inflammatory activity than analgesic and antimicrobial activity.
