Abstract

The reaction of 1-acetyl-2-phenyl-5-hydroxypyrazolidines with pyrazol-5-ones leads to the corresponding 4-(pyrazolidin-5-yl)pyrazolones, which exist mainly in the form of hydroxypyrazoles. The process proceeds on the surface of adsorbents in a nonpolar solvent. The structure and stereochemistry of the bisheterocycles obtained were studied.
