Abstract

The interaction of 1-alkyl-3-alkoxycarbonylpyperidin-4-ones with phenylhydrazine has led to 5-alkyl-2-phenyl-3,3a,4,5,6,7-hexahydro-2H-pyrazolo-[4,3-c]pyridin-3-ones. The prepared compounds are unstable and undergo a series of uncommon transformations; their mechanisms have been suggested basing on the structural analysis of the product mixtures.
