Abstract

Addition of α-alkenylzirconacyclopentenes to aldehyde enables a highly stereoselective synthesis of β-hydroxyallenes with multiple stereogenic centers including allenic axial chirality, as well as center chirality. Remarkably, the reaction occurs with completely different chemoselectivity in comparison with the usual alkyl- or aryl-substituted zirconacyclopentenes.
