Abstract


This review covers the literature on synthesis of polycyclic aromatic hydrocarbons via the Friedel–Crafts/Bradsher cyclization, published in the period of 1987–2016. Syntheses of partly and fully fused (hetero)aromatic systems with 5- or 6-membered rings formed upon the cyclization and containing C, O, S, N ring (hetero)atoms are reported in this work. All described aromatic systems have been formed in reactions using aromatic aldehydes and their derivatives as carbonyl reagents.


Keywords
