A novel strategy for the preparation of ketones from aldehydes and allylic boronic esters is presented. This reaction involves the allylation of aldehydes with allylic boronic esters and the Rh-catalyzed chain-walking of homoallylic alcohols. This approach features mild reaction conditions, broad substrate scope, and excellent functional groups. Mechanistic studies also supported that a tandem allylation
