A Simple and Efficient Method for the Preparation of α-Halogenated Ketones Using Iron(III) Chloride and Iron(III) Bromide as Halogen Sources with Phenyliodonium Diacetate as Oxidant
ketones are both unique structure moieties existing in biologically natural products and valuable synthetic intermediates for the preparation of functional molecules. An efficient and scalable method for the preparation of α‐halogenated ketone using iron (III) chloride and iron (III) bromide as halogen sources with phenyliodonium diacetate as oxidant has been developed, featuring mild reaction conditions

method utilizes the unique reactivity of an intermediate Mg–enolate dianion, which displays selectivity for the carbonyl carbon of chloromethyl carbonyl electrophiles. Decarboxylation of the intermediate occurs spontaneously during the reaction quench. The utility of the reaction products has been demonstrated through the total synthesis of the natural product cimiracemate B.
