Heterocyclic synthesis using nitrilimines: part 14. Synthesis of new pyrazole derivatives
A new series of 1,3,4,5-tetrasubstituted pyrazoles have been synthesized by the 1,3-dipolar cycloaddition of suitable nitrilimines to 3-propylidene and 3-benzylidene-phthalide. Both analytical and spectroscopic data of all the synthesized compounds are in full agreement with the proposed structures.

- In conclusion, we described the 1,3-dipolar cycloadditions of nitrilimines to some exocyclic oleŞns and the results demonstrated that the aromatization was the driving force for the formation of aromatic pyrazole derivatives.
