Tandem [4+2]/[3+2] cycloadditions of nitroalkenes

Tandem reactions are transformations that result in complex systems with increased synthetic efficiency. Cascade or domino reactions and multicomponent cyclizations are examples of tandem reactions. This review focuses on tandem cascade cycloadditions of nitroalkenes for the construction of highly functionalized nitrogen-containing heterocycles. The discussion also includes tandem [4+2]/[3+2] cycloadditions involving other functional groups.
