Oxazole and Isoxazole Chemistry in Crop Protection

An overview is given of the significance of the oxazole and isoxazole scaffolds in crop protection chemistry. The main herbicidally, fungicidally, and insecticidally active oxazole and isoxazole classes are presented, together with their synthesis routes, modes of action, and biological efficacies. In addition, the role of oxazoles and isoxazoles as lead structure or as intermediate in the synthesis of other agrochemicals is reported. Also, partially and fully saturated oxazole and isoxazole derivatives such as oxazolines, isoxazolines, oxazolidines, and isoxazolidines, oxygenated derivatives such as oxazolones and isoxazolones as well as annulated derivatives, such as benzoxazoles and benzisoxazoles, are covered.

Recent progresses in the synthesis of functionalized isoxazoles

Isoxazole is an important pharmacophore that is critical for biological activity. The isoxazole ring ranks 33rd in frequency among the 351 ring systems found in marketed drugs, thus suggesting a great deal of interest in the synthesis of functional isoxazoles. In recent years, various approaches have been developed for the synthesis and functionalization of isoxazoles. This comprehensive survey summarizes the recent new synthetic approaches to functionalized isoxazoles, with particular focus on the last three years with regard to the following reaction types: (1) 1,3-dipolar cycloaddition, (2) condensation, (3) cycloisomerization, and (4) direct functionalization.

Synthesis of isoxazole-containing sulfonamides with potent carbonic anhydrase II and VII inhibitory properties

Two series of benzenesulfonamide containing isoxazole compounds were prepared by using conventional and microwave (MW) methods. 5-Amino-3-aryl-N-(4-sulfamoylphenyl)isoxazole-4-carboxamide derivatives were synthesized by the reaction of hydroxymoyl chlorides with 2-cyano-N-(4-sulfamoylphenyl)acetamide in the presence of triethylamine. The synthesized 5-amino isoxazoles were reacted with various benzoyl chlorides in order to obtain 5-amidoisoxazoles. The novel compounds were screened in vitro as inhibitors of four human (h) isoforms of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1): hCA I, hCA II, hCA IV and hCA VII. The derivatives of the first series were shown to possess excellent inhibitory activity against the cytosolic isoform hCA II, an antiglaucoma drug target, with Kis in the range of 0.5-49.3 nM and hCA VII, a recently validated anti-neuropathic pain target with Kis in the range of 4.3-51.9 nM.

Microwave induced synthesis of a new class of pyrano isoxazoline and isoxazole annulated chromones – an intramolecular nitrile oxide cycloaddition with tethered olefins and alkynes

A variety of new highly substituted 6-6-6-5-membered tetracyclic pyrano isoxazoline/isoxazole annulated chromone derivatives have been synthesized via eco-friendly microwave assisted/ceric ammonium nitrate (CAN) as an oxidant, intramolecular 1,3-dipolar cycloaddition with in situ generated nitrile oxides from aldoximes of alkene/alkyne tethered chromones. This protocol is practically simple and efficient to construct diverse range of substituted pyrano isoxazoline/isoxazole annulated chromone derivatives and gave higher yields of products in microwave irradiation compared to conventional heating. The structures of all the synthesized compounds were established by IR, NMR and MASS spectral analysis. [GRAPHICS]

Synthesis of dithia- and tetrathiacyclophanes incorporating isoxazole units

The reaction of 5-bromomethyl-3-(p-bromomethylphenyl)isoxazole with o-, m-, and p-bis(mercaptomethyl)benzenes gave the corresponding dithia- and/or tetrathiaisoxazolophanes, whose relative yields strongly depended upon the nature of the mercaptomethyl compound. The above isoxazole dibromide reacted with the bis(mercaptomethyl)isoxazole to afford a mixture of two isomeric dithiaisoxazolophanes.

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 17153-20-7, in my other articles.

Isoxazole analogs of curcuminoids with highly potent multidrug-resistant antimycobacterial activity

Curcumin (1), demethoxycurcumin (2) and bisdemethoxycurcumin (3), the curcuminoid constituents of the medicinal plant Curcuma longa L, have been structurally modified to 55 analogs and antimycobacterial activity against Mycobacterium tuberculosis has been evaluated. Among the highly active curcuminoids, the isoxazole analogs are the most active group, with mono-O-methylcurcumin isoxazole (53) being the most active compound (MIC 0.09 mu g/mL). It was 1131-fold more active than curcumin (1), the parent compound, and was approximately 18 and 2-fold more active than the standard drugs kanamycin and isoniazid, respectively. Compound 53 also exhibited high activity against the multidrug-resistant M. tuberculosis clinical Isolates, with the MICs of 0 195-3.125 mu g/mL. The structural requirements for a curcuminoid analog to exhibit antimycobacterial activity are the presence of an isoxazole ring and two unsaturated bonds on the heptyl chain. The presence of a suitable para-alkoxyl group on the aromatic ring which is attached in close proximity to the nitrogen function of the isoxazole ring and a free para-hydroxyl group on another aromatic ring enhances the biological activity.
