Abstract

AbstractThe diastereoselective synthesis of anti‐homoallylic alcohols bearing conjugated (Z)‐enynes through a palladium‐catalyzed three‐component reaction is described. This reaction features a broad substrate scope, good functional group compatibility, and high levels of (Z)‐alkene stereocontrol. In this reaction, Pd(0) functions as a catalyst in two fundamental steps of the tandem sequence: 1) the generation of a borylated π‐allylpalladium species from bifunctional conjunctive reagents, inducing umpolung allylation of aldehydes, and 2) C(sp2)−C(sp) cross‐coupling. Further transformations of the obtained products highlight their synthetic utility.magnified image
