A one‐step homologation protocol for the synthesis of natural products containing deoxypropionate motif is described by the combination of Zr‐catalyzed asymmetric carboalumination of alkenes (ZACA)‐Pd‐catalyzed vinylation and ZACA–oxidation reaction. In contrast to most other synthetic strategies used to date that typically require three steps per deoxypropionate unit due to the functional‐group interconversions
