1,3-Dipolar cycloadditions of 2-thio-3-chloroacrylamides with nitrile oxides and nitrones [PDF]
1,3-Dipolar cycloadditions of 2-thio-3-chloroacrylamides with nitrile oxides and nitrones is described. A series of novel isoxazolines are isolated from the nitrile oxide cycloadditions, whilst the isoxazolines generated from the nitrone cycloadditions ...

Diacylfuroxans Are Masked Nitrile Oxides That Inhibit GPX4 Covalently.
GPX4 represents a promising yet difficult-to-drug therapeutic target for the treatment of, among others, drug-resistant cancers. Although most GPX4 inhibitors rely on a chloroacetamide moiety to modify covalently the protein's catalytic selenocysteine ...

Synthesis, DFT Study and Antibacterial Activity of some Isoxazoline Derivatives Containing 1,4-benzothiazin-3-one Nucleus Obtained Using 1,3-dipolar Cycloaddition Reaction [PDF]
Novel series of isoxazoline derivatives containing 1,4-benzothiazin-3-one ring (6a-h) were synthesized via 1,3-dipolar cycloaddition reactions of arylnitrile oxides 5a-d on 4-allyl-2-(substituted)-1,4-benzothiazin-3-ones 3 and 4 led to polyheterocyclic ...

Inverse electron-demand 1,3-dipolar cycloaddition of nitrile oxide with common nitriles leading to 3-functionalized 1,2,4-oxadiazoles [PDF]
A carbamoyl-substituted nitrile oxide was generated upon treatment of easily available 2-methyl-4-nitro-3-isoxazolin-5(2H)-one with THF (not dried); the reaction proceeded efficiently even in the absence of any special reagents and reaction conditions ...

An anomalous hydration/dehydration sequence for the mild generation of a nitrile oxide [PDF]
A nitrile oxide containing a carbamoyl group is readily generated upon the treatment of 2-methyl-4-nitro-3-isoxazolin-5(2H)-one with water under mild reaction conditions, even in the absence of special reagents.

Functionalisation of Artemisinin and Its Ring-contracted Derivatives
Isoxazoline analogues of artemisinin were obtained in low yield and low diastereoselectivity from the 1,3-dipolar cycloaddition of nitrile oxides. Alternatively, starting from the aldehyde 7, a number of transformations - Wittig reaction and reduction ...

Synthesis of 3,5-Disubstituted Isoxazoles and Isoxazolines in Deep Eutectic Solvents [PDF]
The synthesis of different 3,5-disubstituted isoxazoles and related isoxazolines using choline chloride:urea as deep eutectic solvent (DES) in a one-pot three step reaction has been accomplished successfully. The use of highly nucleophilic functionalized
