The Reactions of Azines on Treatment with 1,3-Bifunctional Nucleophiles

The literature data on the o-cyclisation reactions of azines with 1,3-bifunctional nucleophiles, which make it possible to annelate furan, pyrrole, imidazole, and other five-membered rings to an aromatic aza-ring are surveyed and described systematically. The cyclisation reactions leading to m-linked cyclic adducts or products of the transformation of azines via the intermediate formation of cyclic m- and p-adducts are also examined.
