1,3-Dipolar cycloaddition of nitrones: synthesis of multisubstituted, diverse range of heterocyclic compounds
*a
Abstract
Cycloadditions are known to be one of the most abundant, versatile and valuable classes of chemical reactions. Among various efficient chemical processes, cycloaddition is an important route owing to its stereospecificity, ability to generate complex molecules and atom economy. Nitrone is one of the widely used dipoles in the 1,3-dipolar cycloaddition reaction, as it is stable and does not always require in situ generation. The 1,3-dipolar cycloaddition of nitrones with various dipolarophiles generates several heterocyclic rings having different sizes. These heterocycles have enormous applications in natural products, biologically active molecules and pharmaceuticals. This review is focused on nitrones that undergo cycloaddition with different substrates to generate various heterocyclic rings.
