onamide or celecoxib (6) in 30% yield. However, under identical conditions, synthesis of [11C]celecoxib ([11C]6) was unsuccessful. Instead, trapping [11C]CH3I in an argon purged solution of catalytic amounts of Pd2(dba)3 and tri-o-tolylphosphine followed by the addition of the precursor 5 in DMF under argon and heating the mixture at 135°C for 4 min resulted in the incorporation of [11C]CH3 group.

The combined use of 1H NMR spectroscopy with theoretical calculations of chemical shifts (GIAO) and coupling constants (B3LYP/6‐311 ++G**) of a 5‐hydroxy‐5‐trifluoromethyl‐Δ2‐isoxazoline has enabled solving the problem of the assignments of the diastereotopic protons in this compound. This result has been extended to 5‐hydroxy‐5‐trifluoromethyl‐Δ2‐pyrazolines and the corresponding 5‐trichloromethyl
A highlyregioselectivesynthesis of 1-aryl-3,4,5-substituted pyrazoles based on the condensation of 1,3-diketones with arylhydrazines is described. The reaction proceeds at room temperature in N,N-dimethylacetamide and furnishes pyrazoles in 59-98% yields.
