A facile access to 1,3,4-trisubstituted pyrazoles via 1,3-dipolar cycloaddition of 3-arylsydnones with α,β-unsaturated ketones

A novel one-pot synthesis of 1,3,4-trisubstituted pyrazoles has been accomplished by 1,3-dipolar cycloaddition of α,β-unsaturated ketones and 3-arylsydnones in dry xylene. The structural identities of these compounds were confirmed on the basis of IR, NMR, mass spectral, and X-ray analysis.
