Abstract

The room temperature, 1,3-dipolar cycloaddition reactions of the nitrile oxide obtained from (6-piperidin-1-yl-9H-purin-9-yl)acetaldehyde oxime upon phenyliodine(III) bis(trifluoroacetate) treatment with excess unsaturated alcohols as solvent resulted in isoxazoline or isoxazole derivatives in almost quantitative yields. Analogous derivatives were prepared from the reactions of unsaturated phosphates. Preliminary biological tests indicated inhibition of lipid peroxidation for some of the examined compounds.
