Abstract

Abstract : An intramolecular Minisci acylation under silver-free neutral conditions providing access to azafluorenones and fluorenones has been developed. Abstract : Despite its synthetic potential, intramolecular acylation by the Minisci reaction remains unexplored. The development of a new intramolecular Minisci acylation under silver-free neutral conditions providing access to azafluorenones and fluorenones is described. Distinct from the current literature known approaches for Minisci acylation, the report described herein features a method that: (a) avoids the use of silver that is invariably used in Minisci acylation, (b) does not require any acidic conditions for the activation of pyridines, and (c) shows tolerance to functional groups under neutral conditions.
