Research Progress on [3+n](n >= 3) cycloaddition of 1,3-Diploes
Versatile heterocyclic skeletons extensively exist in structures of natural products, drug molecules and organic materials, and have been synthesized through various strategies reported in literatures. Among them, the 1,3-dipolar cycloaddition is the most impressive class to build the related heterocycles. In the past, organic chemists generally employed [3+2] cycloaddition of 1,3-dipoles to assemble five-membered rings. As modern chemistry developes, researchers further turn their attention to the [3+3], [3+4], [3+5] and [3+6] cycloadditions, to construct six-, seven-, eight- and bridge-heterocyclic compounds. At present, review articles with topics on 1,3-dipolar cycloaddition mainly focus on [3+2] cycloaddition. Herein, A topic on [3 + n] (n >= 3) cycloaddition of 1,3-dipoles, with comments on the developed methodologies is present and the out-look in this field is proposed.
