Desymmetrization of meso-2-Alkene-1,4-diol Derivatives through Copper(I)-Catalyzed Asymmetric Boryl Substitution and Stereoselective Allylation of Aldehydes
Breaking the mirror: The reaction sequence described in the title was applied to the synthesis of a valuable chiral drug precursor and the rapid stereoselective assembly of complex compounds with multiple chiral centers (see scheme).
