THE STATE OF ART IN SYDNONES CHEMISTRY AND APPLICATIONS

摘要

Sydnones are mesoionic stable compounds firstly synthesized more than 80 years ago. Their aromatic behavior as well as their property to give 1,3-cycloaddition reactions make these compounds a valuable tool for the synthesis of new heterocycles having complex structures. The bioactivity of numerous sydnones, or the heterocycles resulted from them, explains easily the interest for these compounds reflected also by numerous publications in this area. The present review analyzes the recent syntheses, reactions and applications of sydnones, since 2010. The subject was of interest for a number of researchers from the Centre of Organic Chemistry for a long time and it is still included in their research area.
