The Journal of Organic Chemistry, 2019 The first synthesis of isoxazole-4-carboxylic acid derivatives by domino isoxazole-isoxazole isomerization is reported. Fe(II)-catalyzed isomerization of 4-acyl-5-methoxy-/5-aminoisoxazoles (dioxane, 105 °C) leads to the formation of isoxazole-4-carboxylic esters and amides in good yields. 4-Formyl-5-methoxyisoxazoles give methyl oxazole-4-carboxylates

Design and synthesis of novel isoxazole-based HDAC inhibitors
European Journal of Medicinal Chemistry, 2010 A series of isoxazole-based histone deacetylase (HDAC) inhibitors structurally related to SAHA were designed and synthesized. The isoxazole moiety was inserted in the vicinity of the Zn2+-binding group in order to check its participation in the ...

A series of 3-halo-5-phenyl- and 3-phenyl-5-haloisoxazoles has demonstrated anthelmintic activity at doses ranging from 16 to 500 mg/kg orally against the rat roundworm, Nippostrongylus braziliensis. In the 5-phenyl series a halogen at the 3 position of the isoxazole ring was required for activity.

NH2OH–Mediated Lignin Conversion to Isoxazole and Nitrile
ACS Sustainable Chemistry and Engineering, 2018 Conversion of lignin to aromatic compounds via C-C/C-O bond cleavage has been an attractive but challenging subject in recent years. We herein report the first protocol that converts lignin models and preoxidized lignin to isoxazole and aromatic nitrile.

Publisher Summary Natural products based on the isoxazole (1,2-oxazole) skeleton constitute a small, heterogeneous group of natural products encompassing at present more than 90 structures. This group has not traditionally been classified as a special alkaloid group and has never been reviewed as a group previously.

Isoxazoles with antipicornavirus activity
Journal of Medicinal Chemistry, 1985The synthesis and evaluation of a series of 3,5-disubstituted isoxazoles as antipicornavirus agents have led to the discovery of several compounds effective in vitro against rhinovirus type 2 and poliovirus type 2. Compound 32 was found more effective than 4',6-dichloroflavan against both viruses and was evaluated orally in mice infected ...
