Abstract

The interaction of 1-acetyl-2-phenyl-5-hydroxypyrazolidines with esters of carboxylic acids, having an electron-acceptor group in the β-position, proceeds under neutral conditions on the surface of adsorbents without preliminary activation. The diastereomeric composition of the isomers obtained was determined for derivatives of cyanacetic and nitroacetic esters; the derivative of acetoacetic ester shows keto‒enol tautomerism in solution. The possibility of activation of the reactions on the surface of the adsorbent with uhf irradiation was shown.
