Abstract

A new and general synthesis of polycyclic fluoranthenes is described. The key step is a Michael addition of 9-fluorenyl anion to α-methylene ketones, followed by cyclodehydration and aromatization. The versatility of this synthetic strategy was demonstrated by the preparation of several substituted fluoranthenes and polycyclic fluoranthenes. The sterically-driven double Wagner-Meerwein rearrangement in the synthesis of this class of molecules is also discussed.
