Enantioselective Rhodium-Catalyzed Alkylative Desymmetrization of 3,5-Dimethylglutaric Anhydride

A rhodium-catalyzed enantioselective cross-coupling of sp³ organozinc reagents and 3,5-dimethylglutaric anhydride has been developed to afford the corresponding products, syn-deoxypolypropionates, in excellent yields and enantioselectivities. This reaction has been developed so that both commercially available and in situ prepared organozinc reagents are competent coupling partners.
