Enamines in Heterocyclic Synthesis: A Route to 4-Substituted Pyrazoles and Condensed Pyrazoles
View through CrossRef
Abstract
The reaction of nitrile imines, generated in situ, from hydrazonoyl halides 3a - e with enamines 2a - c affords pyrazoles 8a - g. These pyrazoles have been used to prepare condensed pyrazoles.
