Synthesis of 1,4‐Diketones from β‐Oxo Esters and Enol Acetates by Cerium‐Catalyzed Oxidative Umpolung Reaction†.
Ontology highlight
ABSTRACT: AbstractCyclic β‐oxo esters are converted with enol acetates in a cerium‐catalyzed, oxidative Umpolung reaction to furnish 1,4‐diketones with up to 95 % yield. Atmospheric oxygen is the oxidant in this process, which can be regarded as ideal from economic and ecological points of view. Further advantages of this new C–C coupling reaction are its operational simplicity and the application of nontoxic and inexpensive CeCl 7HO as precatalyst.
