Synthesis of 5-isoxazol-5-yl-2 ‘-deoxyuridines exhibiting antiviral activity against HSV and several RNA viruses

This paper describes a simple method for synthesizing a small library of 5-isoxazol-5-yl-2 ‘-deoxyuridines from 5-iodo-2 ‘-deoxyuridine. Nitrile oxides were generated in situ from oximes using a commercial bleaching agent; their cycloaddition with 5-ethynyl-2 ‘-deoxyuridine yielded isoxazoles possessing activity against herpes simplex viruses 1 and 2, Encephalomyocarditis virus, Coxsackie B3, and vesicular stomatitis virus; these isoxazoles were, however, inactive against corona virus, influenza virus, and HIV.

SYNTHESIS AND HERBICIDAL ACTIVITY OF 3-ARYL-5-(HALOALKYL)-4-ISOXAZOLECARBOXAMIDES AND THEIR DERIVATIVES

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.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 71119-23-8. HPLC of Formula: C6H12NNaO4S.

Efficient Synthesis and Properties of a Photochromic Diarylethene Bearing Thiophene and Isoxazole Moieties

A novel photochromic diarylethene based on isoxazole moiety was synthesized and its photochromic and fluorescent properties were also investigated. This compound exhibited reversible photochromism, changing from colorless to red after irradiation with UV light both in solution and in poly-methyl methacrylate (PMMA) amorphous film. Also, it exhibited remarkable fluorescence switching in the solid state. The results showed that the diarylethene exhibited a relatively strong fluorescence switch along with the photochromism from open-ring isomer to closed-ring isomer. Using this dithienylethene 1c as optical storage was performed successfully.

Synthesis of S-triazolo[3,4-b]-1,3,4-thiadiazine, imidazolo[2,1-b]1,3,4-thiadiazole and imidazolo[2,1-b]-1,3,4-oxadiazole derivatives containing isoxazole

Isoxazole derivatives were characterized by broad spectrum of biological activities, but the condensed heterocyclic compounds containing isoxazole were scarcely reported. In this paper, we studied the 1,3-dipolar cycloaddition of p-methoxybenzohydroxamoyl chloride with ethyl sodioacetoacetate to obtain a key intermediate 2. Through compound 2, fifteen novel S-triazolo[3,4-b]-1,3,4-thiadiazines (5a-5e), imidazolo[2,1-b]-1,3,4-thiadiazoles (9a-9e) and imidazolo[2,1-b]-1,3,4-oxadiazoles (10a-10e) containing isoxazole, which have potentially useful biological activities, were synthesized. The structures of the products were confirmed by elemental analyses and spectral analysis. And the characteristic data of IR, H-1 NMR and MS were explained reasonably.

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).

Vacuum ultraviolet photoionization and ionic fragmentation of the isoxazole molecules

The photofragmentation of the isoxazole molecules producing ionized atomic and molecular fragments was investigated in the photon energy range of 9-32 eV, using synchrotron radiation excitation combined with ion time-of-flight spectrometry. Twenty-one well resolved cations were identified in the mass spectra of the isoxazole, and their appearance energies were determined. The yield curves of these cations were obtained in the photon energy ranges from their appearance energies up to 32 eV. Moreover, the total ion yield of isoxazole was recorded with high precision in the photon energy range of 9.9-10.5 eV. This allowed the determination of the adiabatic ionization energy of 9.96 (0.02) eV in excellent agreement with earlier spectroscopic studies. Our results show that the dissociative ionization of isoxazole starts from the ring-opening and isomerization of isoxazole, and further it follows strictly through its ionic states. Possible ionic fragmentation channels yielding particular ions are discussed. (C) 2019 Elsevier B.V. All rights reserved.
