Iron-catalyzed carbonylative alkyl-acylation of heteroarenes

Abstract Herein we present an efficient carbonylative protocol for the introduction of an alkyl-acyl group into heteroarenes from cyclobutanone oximes. In the presence of Fe(OTf) 2 catalyst, proceeds via intermolecular alkyl-acylation of different heteroarenes. A broad range of alkyl heteroaryl ketones are synthesized with excellent functional group tolerance with good chemoselectivity.
