Preparation and charactrisation of 1, 3-dipolar cycloaddition of nitrones with 4-amino antipyrene

Abstract EN

Some nitrones (1-5), derived from N–phenyl hydroxylamine with substituted benzaldehyde such as (3-chlorobenzaldehyde, 4-chlorobenzaldehyde, 3-nitrobenzaldehyde, 4-florobenzaldehyde, 2-nitrobenzaldehyde).

In subsequent 1,3-dipolar cycloaddition reactions of nitrones with 4-amino antipyrene give isoxazolidines (6-10), They have been identified by 1HNMR, 13CNMR, IR and Mass spectra keyword: nitrones, isoxazolidines, 1,3-dipolar cycloaddition, dipolarophile , heterocycles, benzaldehyde, N–phenyl hedroxyl amine, 4-amino antipyrene
