Synthesis of 3-Nitroisoxazoles via Copper Acetate-Mediated Reaction of Benzaldehydes with Nitromethane

A copper acetate-mediated reaction of benzaldehydes with nitromethane to synthesis of 3-nitroisoxazoles is reported. A variety of nitro-aryl-disubstituted isoxazole derivatives can be prepared in moderate to good yields with benign functional group tolerance. This protocol is successfully applied in gram-scale reaction. Preliminary mechanistic studies reveal that the aldehyde provided one carbon atom for the isoxazole ring, and nitromethane provided two carbon atoms and one nitrogen atom for the isoxazole ring. In this protocol, the C-O-N unit in the final isoxazole ring is formed from the rearrangement of nitromethane.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 82717-96-2, in my other articles.

A series of 4-substituted 3-aryl-5-trifluoromethyl-4,5-dihydroisoxazole derivatives was synthesized by selective reduction of the corresponding 3-aryl-5-trifluoromethyl-4-isoxazole with NaBH4 under various reaction conditions. It was found that the reduction selectivity of endocyclic carbon-carbon double bond of the isoxazole ring was strongly dependent on the electronic effects of substituents at C-4 of trifluoromethylated isoxazoles. Meanwhile, the solvent effects also had a great influence on the reduction selectivity of endocyclic carbon carbon double bond of the 4-iminoyl substituted isoxazole ring.

Green multicomponent synthesis, antimicrobial and antioxidant evaluation of novel 5-amino-isoxazole-4-carbonitriles

Background: Design and synthesis of new inhibitor agents to deal with pathogenic microorganisms is expanding. In this project, an efficient, environmentally friendly, economical, rapid and mild procedure was developed for the synthesis of novel functionalized isoxazole derivatives as antimicrobial potentials. Methods: Multicomponent reaction between malononitrile (1), hydroxylamine hydrochloride (2) and different aryl or heteroaryl aldehydes 3a-i afforded novel 5-amino-isoxazole-4-carbonitriles 4a-i in good product yields and short reaction times. Deep eutectic solvent K2CO3/glycerol was used as catalytic reaction media. Structure of all molecules were characterized by different analytical tools. In vitro inhibitory activity of all derivatives was evaluated against a variety of pathogenic bacteria including both Gram-negative and Gram-positive strains as well as some fungi. In addition, their free radical scavenging activities were assessed against DPPH. Results: Broad-spectrum antimicrobial activities were observed with isoxazoles 4a, b, d. In addition, antioxidant activity of isoxazole 4i was proven on DPPH. Conclusions: In this project, compounds 4a, b, d could efficiently inhibit the growth of various bacterial and fungal pathogens. Antioxidant properties of derivative 4i were also significant. These biologically active compounds are suitable candidates to synthesize new prodrugs and drugs due to the presence of different functional groups on their rings.
