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.

Ligand-biased ensemble receptor docking (LigBEnD): a hybrid ligand/receptor structure-based approach. [PDF]
Ligand docking to flexible protein molecules can be efficiently carried out through ensemble docking to multiple protein conformations, either from experimental X-ray structures or from in silico simulations.

5-(Benzoyloxymethyl)isoxazole-3-carboxylic Acid Ethyl Ester
We describe here the palladium hydrogenation of ethyl 5-(benzoyloxymethyl)isoxazole-3-carboxylate. The presence of two reducible sites in the molecule, namely the benzylic-like position and the isoxazole N–O bond, creates a possible competition.

Ring-Opening Fluorination of Isoxazoles
A ring-opening fluorination of isoxazoles has been developed. By treating isoxazoles with an electrophilic fluorinating agent (Selectfluor®), fluorination followed by deprotonation leads to tertiary fluorinated carbonyl compounds. The present method features mild reaction conditions, good functional group tolerance, and simple experimental procedure ...

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

Side-chain Modifications of Highly Functionalized 3(2H)-Furanones
A series of 3(2H)-furanones, based on side-chain modifications of a parent 3(2H)-furanone, was synthesized in good yield. The parent compound was prepared by hydrogenolysis, and subsequent acid hydrolysis, of isoxazole derivatives.

Development of a triclosan scaffold which allows for adaptations on both the A- and B-ring for transport peptides [PDF]
The enoyl acyl-carrier protein reductase (ENR) enzyme is harbored within the apicoplast of apicomplexan parasites providing a significant challenge for drug delivery, which may be overcome through the addition of transductive peptides, which facilitates ...
