Introduction In recent decades novel reactions based on conjugated nitroalkenes CNA as the key substrates have emerged and numerous challenging targets have been achieved. This was possible primarily due to the ease of preparation or ready availability and the diverse reactivity of nitroalkenes. Moreover the presence of the nitro group allows to obtain bioactivity and useful building blocks for organic 3 Cycloadditions are one of the most important transformations in organic chemical synthesis and are a universal method of preparation of many heterocyclic 10 This work is an attempt to synthetically discuss the results of research in the field of cycloadditions of conjugated nitroalkenes. 2.
