Synthesis of 3-phenyl-5-(trifluoromethyl)isoxazole and 5-phenyl-3-(trifluoromethyl)isoxazole

Reaction of 4,4,4-trifluoro-1-phenyl-1,3-butanedione with hydroxylamine led to the formation of 5-hydroxy-3-phenyl-5-(trifluoromethyl)-4,5-dihydroisoxazole which was dehydrated to 3-phenyl-5-(trifluoromethyl)isoxazole. This isomer can also be synthesized by reaction of 4-chloro-4-phenyl-1,1,1-trifluoro-3-buten-2-one with sodium azide. The regioisomer, 5-phenyl-3-(trifluoromethyl)isoxazole was synthesized by reaction of 1,1,1-trifluoro-4-phenylbut-3-yn-2-one with hydroxylamine and by the reaction of 3-chloro-1-phenyl-4,4,4-trifluorobut-2-en-1-one with sodium azide. Both isomers were characterized by mass and NMR spectroscopy.

Mechanism of the migration of the substituent in 1,2,3,7a-tetrahydroimidazo[1,2-b]isoxazole derivatives

The thermolysis of 1,2,3,7a-tetrahydroimidazo[1,2-b]isoxazole derivatives results in intramolecular rearrangements by two main pathways. One rearrangement affords azomethine ylide derivatives. Another rearrangement leads to the migration of the substituent from position 7a to the nitrogen atom. The rate constants of these reactions were determined. Quantum chemical calculations by the DFT method were carried out. Based on the data for the migration of the substituent, the concerted mechanism was proposed.

Development of 4-oxime-1,8-naphthalimide as a bioorthogonal turn-on probe for fluorogenic protein labeling

4-Oxime-1,8-naphthalimide was reported as a novel bioorthogonal turn-on probe based on 1,3-dipolar cycloaddition reactions between in situ generated nitrile oxide and alkenes/alkynes. The resulting isoxazole products displayed dramatically strong fluorescence enhancement upon photoirradiation through isoxazole-oxazole photoisomerization. This new methodology was successfully applied for in situ fluorogenic protein labeling.

Synthesis and Characterization of Isoxazole-Based Energetic Plasticizer Candidates EEIN and IDN

This study presents the synthesis of ethyl 5-[(nitrooxy)methyl]isoxazole-3-carboxylate (EEIN) and isoxazole-3,5-diylbis(methylene) dinitrate (IDN). These compounds, each derived from 5-(hydroxymethyl)isoxazole-3-carboxylate, were fully characterized and their explosive sensitivity properties were determined. EEIN was isolated as a solid material with a relatively low melting temperature and IDN was isolated as a liquid with excellent energetic performance properties. In addition, we report the molecular structure of ethyl 5-[(nitrooxy)methyl]isoxazole-3-carboxylate as determined by single-crystal X-ray diffractometry. These compounds possess promising properties as plasticizing ingredients in propellant formulations.

Isoxazole ring as a useful scaffold in a search for new therapeutic agents

Due to its relatively easy synthesis, isoxazole ring has been as an object of interest for chemists and pharmacologists from research groups all over the world. Its chemical modifications include both connection of isoxazole with other aromatic, heteroaromatic or non aromatic rings and substitution with different alkyl groups. Thanks to their usually low cytotoxicity, isoxazole derivatives are still popular scaffolds for the development of new agents with variable biological activities, such as antimicrobial, antiviral, anticancer, anti-inflammatory, immunomodulatory, anticonvulsant or anti-diabetic properties. This review discusses the chemical structure of recently developed isoxazole derivatives with regards to their activity and potential therapeutic use. (C) 2017 Elsevier Masson SAS.

Interesting results of catalytic hydrogenation of 3-(2-nitrophenyl)isoxazoles and 3-(nitrophenyl)-4,5-dihydroisoxazoles

The palladium-on-carbon assisted hydrogenolysis of substituted 3-(2-nitrophenyl)isoxazoles, irrespective of substitution on the isoxazole ring, invariably leads to reduction of the nitro to the amino group with concomitant regiospecific ring closure to yield substituted 4-aminoquinolines. In contrast similar hydrogenation of 3-(2-, 3-, and 4-nitrophenyl)-4,5-dihydroisoxazoles (2-isoxazolines) results in reduction of the nitro group only with conservation of the dihydroisoxazole ring to yield the corresponding 3-(aminophenyl)-4,5-dihydroisoxazoles.
