alkenylimidazoles, synthesis methods, condensation, chemical properties, heterocyclofunctionalization


The aim of this review was to summarize and systematize literature on chemistry of alkenylsubstituted imidazoles known as important synthetic substrates and precursors for the synthesis of biologically active substances. Two approaches to the synthesis of these compounds are reviewed: 1) the imidazole ring formation based on functionalized alkenyl compounds; 2) functionalization of imidazole derivatives with the alkenyl moiety. The second approach prevails and includes condensation of methylimidazoles with carbonyl compounds, reactions of formylimidazoles with compounds containing activated methylene groups and phosphorus ylides, as well as reactions of dehydration and dehydrohalogenation of substituted imidazoles. The methods of synthesis of alkenylsubstituted imidazoles have been analyzed in detail; their synthetic potential and limits have been described. Special attention is paid to the authors’ own research on the synthesis of new 4-chloro-5-alkenylsubstituted imidazoles using 5-formylimidazoles as precursors. Analysis of the chemical properties of alkenylsubstituted imidazoles has allowed conducting their strict classification and systematizing their typical transformations. Reactions of cyclocondensation are the first ones to be mentioned, they proceed through the interaction of the alkenyl moiety with another functional group or endocyclic Nitrogen. Other transformations such as heterocyclofunctionalization, oxidation and reduction are based on transformation of the alkenyl moiety. It should be noted that heterocyclization processes are new for chemistry of alkenylimidazoles, they are successfully applied to 5-(2-nitro-alkenyl)- and 5-(2-arylvinyl)substituted derivatives, and due to them it is possible to obtain new promising hybrid structures.
