Abstract

1,3-Dipolar cycloaddition reaction of aldonitrones such as C-2-furyl-N-phenyl-, C,N-diphenyl-, and C-2-thienyl-N-phenylnitrone with N-phenylmaleimide was carried out. The product was separated into two stereo isomers, cis and trans isoxazolidines with respect to H3 and H4, which were identified by NMR spectra. Spin-spin coupling of protons on C3 and C4 of isoxazolidine ring was found to be 8.4–9.0 cps for cis isomers and to be zero for trans isomers.
