The 1,3-dipolar cycloaddition of nitrileoxides generated in situ from benzohydroximinoylchloride and triethylamine to 2-aminopyranopyridine-3-carbonitriles and 2-aminochromene-3-carbonitriles occurred chemoselectively furnishing novel 1,2,4-oxadiazole-pyranopyridine/chromene hybrid heterocycles in moderate yields.
