Cycloaddition of diazomethane and ethyl diazoacetate to a-(diethoxyphosphoryl)vinyl p-tolyl sulfoxide la and its P-substituted analogues (Me, Ph) results in the formation of 3-phosphorylpyrazoles in high yield. The reaction of chiral (S)-(+tla with diphenyldiazomethane proceeds fYly diastereoselecti
