Synthesis of 5-hydroxy- and 5-acylhydrazinopyrazolidines by the reaction of β-substituted hydrazides with α,β-unsaturated aldehydes and their biological activity

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The reaction of β-substituted hydrazides with alkenals (acrolein, methacrolein, crotonaldehyde, and cinnamaldehyde) serves as a method for the synthesis of the corresponding 1-acyl-5-hydroxypyrazolidines and, in a number of cases, 1-acyl-5-acylhydrazinopyrazolidines. Some of the 1-acyl-5-hydroxypyrazolidines obtained have antiphlogistic activity.
