Synthesis of 3-cyano-4,6-dinitrobenzo[d]isoxazole and its reactions with anionic nucleophiles

The action of various anionic O-, N-, and S-nucleophiles on 3-cyano-4,6-dinitro-benzo-[d]isoxazole mostly resulted in regiospecific nucleophilic substitution for the nitro group in position 4. With an excess of an nucleophilic reagent, the nitro group in position 6 was also replaced.

Elucidation of a Novel Bioactivation Pathway of a 3,4-Unsubstituted Isoxazole in Human Liver Microsomes: Formation of a Glutathione Adduct of a Cyanoacrolein Derivative after Isoxazole Ring Opening

Studies on the biotransformation of isoxazole rings have shown that molecules containing a C3-substituted isoxazole or a 1,2-benzisoxazole can undergo a two-electron reductive ring cleavage to form an imine. In the absence of a C3 substituent, the isoxazole ring opens via deprotonation of the C3 proton followed by N-O bond cleavage to yield an alpha-cyanoenol analog. We report the identification of a novel bioactivation pathway of a 3,4-unsubstituted isoxazole in human liver microsomes. After the enzyme-catalyzed cleavage of the 3,4-unsubstituted isoxazole ring of N-((2-isopropyl-7-methyl-1-oxoisoindolin-5-yl)methyl)isoxazole-5-carboxamide (P) in human liver microsomes, the formed alpha-cyanoenol (M1) condenses with formaldehyde to generate an alpha,beta-unsaturated Michael acceptor intermediate (a cyanoacrolein derivative, VII), which further reacts with the cysteinyl thiol of glutathione to yield a GSH adduct of a cyanoacrolein derivative (M3). The same adduct also is formed when M1, generated in 0.1 N NaOH aqueous solution, reacts with formaldehyde and GSH. (13)C-labeled methanol was used to confirm that methanol from the drug stock solution was oxidized by liver microsomal enzymes to formaldehyde and the carbon atom from methanol was finally incorporated in the corresponding GSH adduct. The formation of isoxazole ring-opened products (M1 and M2) in human liver microsomes is NADPH-dependent. M1 and M2 were found in human liver microsomes preincubated with 1-aminobenzotriazole (1 mM) and NADPH (5 mM) at similar to 10% of the levels found in the samples in the absence of 1-aminobenzotriazole, suggesting that this biotransformation pathway is primarily catalyzed by cytochrome P450. The formation of M3 also was inhibited by 1-aminobenzotriazole at a similar level.

3-(Arylthiomethyl)isoxazole-4,5-dicarboxamides: Chemoselective Nucleophilic Chemistry and Insecticidal Activity

A collection of 91 3-(arylthiomethyl)isoxazole-4,5-dicarboxamides was prepared starting from dimethyl 3-(chloromethyl)isoxazole-4,5-dicarboxylate. The thioether moieties in these compounds were subsequently oxidized to give the corresponding 3-(arylsulfonylmethyl)isoxazole-4,5-dicarboxamides. By carefully controlling stoichiometry and reaction conditions, the C4 and C5 carbomethoxy groups could be differentially derivatized to carboxamides. A total of 182 trisubstituted isoxazoles are reported and deposited in the National Institutes of Health Molecular Repository; an 80 compound subset was evaluated for insecticidal activity.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 622-40-2, you can contact me at any time and look forward to more communication. Category: Isoxazoles.

MAGNESIUM BROMIDE AN EFFICIENT CATALYSTS FOR THE SYNTHESIS OF 3,4-DISUBSTITUTED ISOXAZOLE-5(4H)-ONES

A one-pot and three component synthesis of 3-mehyl-4-arylmethyleneisoxazol-5(4H)-ones was developed in the presence of magnesium bromide as the catalyst. The products were obtained in high yields and short reaction time, with easy workup process. The present method provides an easy and efficient approach for the synthesis of this class of compounds, because of its clean reaction profile and operational simplicity.

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 446292-10-0, in my other articles.

A Novel Photochromic Diarylethene Based on Thiophene and Isoxazole Moieties for Optical Recording

A novel photochromic diarylethene based on isoxazole moiety was synthesized and its photochromic and fluorescent properties were also investigated. It underwent reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light in hexane and in PMMA film. The compound exhibited remarkable photochromism, changing from colorless to purple after irradiation with UV light. When irradiation with UV light, the fluorescence intensity declined remarkably. 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.

C5-Modified nucleosides exhibiting anticancer activity

We describe (i) a simple method for the synthesis of C5-modified nucleosides from 5-iodo-2’deoxyuridine and (ii) their activity against six types of human cancer cell lines (HCT15, MM231, NCI-H23, NUGC-3, PC-3, ACHN). We generated nitrile oxides in situ from oximes using a commercial bleaching agent; their cycloadditions with 5-ethynyl-2′-deoxyuridine yielded isoxazole derivatives possessing activity against the cancer cell lines. We synthesized several azides from benzylic bromides and their click reactions with 5-ethynyl-2′-deoxyuridine provided triazole derivatives. (C) 2009 Elsevier Ltd. All rights reserved.
