Abstract
This review summarizes the reactions of nitrilimines, genearted in situ by base-catalyzed dehydrohalogenation of the respective hydrazonoyl halides, with aminoazoles, aminoazines and various types of enamines. It also presents the highlights of recent developments in the utility of such reactions for synthesis of a variety of heterocycles which are not obtainable by other synthetic means. Such reactions provide convenient strategies for synthesis and annulation of heterocycles. It covers the literature from 1985 to mid 2006.
