1,3‐Dipolar cycloaddition of the nitrilimines with the 2‐propylidene‐3‐coumaranone afforded the corresponding pyrazole derivatives. Similar reactions of nitrilimines with 3‐ethylidene‐1‐indanone furnished spiropyrazoline derivatives. The spectral data of the synthesized compounds are in full agreement with its molecular structure.
