摘要：
A novel one-pot synthesis of 1,3,4-trisubstituted pyrazoles has been accomplished by 1,3-dipolar cycloaddition of alpha,beta-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.
