Reaction of 3-methyl-4-nitro-5-alkylisoxazoles with hydroxylamine provides a practical means to interchange the N,O-heteroatoms on the isoxazole core thereby expanding the range of compounds obtainable from 3-methyl-4-nitro-5-styrylisoxazoles.

Herein we described the preparation of two novel heterocyclic nuclei isoxazolopyridone and pyrazolopyridone. The syntheses are modular in nature and fast to execute. The title compounds were obtained pure without intervention of chromatography.

The expected Michael adducts and spiroisoxazolines are obtained from the reaction between 3-methyl-4-nitro-5-styrylisoxazole and bis-enolisable ketones. Contrary to reported data, Michael adducts are obtained in good yields only when a substoichiomet

A method allowing the selective oxygen labelling of aliphatic polyacids, for example, succinic and glutaric acids, is reported. This process is based on the hydrolysis of a 3-alkyl-4-nitroisoxazol-5-yl group by Na 18 OH and affords the products in hi

The title compound, C 24 H 20 N 4 O 6 , is a dimer obtained by irradiation of 3-methyl-4-nitro-5-styrylisoxazole. The relative configuration of the stereocentres and the conformation of the 2-oxa-3-azabicycloheptene ring is established

The acinitro group in the title compound, C6H16N+·C17H17N2O5−, is almost coplanar with the isoxazoline ring, which assumes a flattened envelope conformation. The cyclohexanone ring adopts a half-chair conformation and carries a perpendicular [

Herein we described an optimised synthesis of isoxazoloazepinone and novel heterocycle pyrazoloazepinone. These syntheses are modular in nature and fast to execute. The title compounds were obtained pure without the intervention of chromatography.
