    Abstract We report herein a Cu‐catalyzed regio‐, diastereo‐ and enantioselective acylboration of 1,3‐butadienylboronate with acyl fluorides. Under the developed conditions, the reactions provide (Z)‐β,γ‐unsaturated ketones bearing an α‐tertiary stereocenter with highZ‐selectivity and excellent enantioselectivities. While direct access to highly enantioenrichedE‐isomers was not successful, we showed that such molecules can be synthesized with excellentE‐selectivity and optical purities via Pd‐catalyzed alkene isomerization from the correspondingZ‐isomers. The orthogonal chemical reactivities of the functional groups embedded in the ketone products allow for diverse chemoselective transformations, which provides a valuable platform for further derivatization.
