A concise and efficient synthesis of imidazo[1,2,4]oxadiazole derivatives that proceeds through the [3+2] cycloaddition of 2‐chloro‐1 H ‐benzo[ d ]imidazole with nitrile oxides has been developed. This strategy can conveniently construct tricyclic imidazole heterocyclic derivatives that contain a broad range of functional groups. Compound 3 p showed excellent cytotoxic activity against the KYSE410 cell line (IC 50 =0.26 μ m ). These tricyclic imidazole heterocyclic derivatives are promising candidates for drug discovery.
