Abstract

First representatives of pyrazolines were synthesized in the last century. These nitrogen-containing heterocyclic compounds became important in the development of different bioactive substances. For this reason, various procedures have been worked out for their synthesis. In the present review article we have planned to summarize those synthetic methods providing 1- or 2-pyrazolines by the reactions of α,β-unsaturated ketones with diazoraethane or hydrazine derivatives.
