some of the examined compounds. 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
