Enantioselective 1,2-Difunctionalization of 1,3-Butadiene by Sequential Alkylation and Carbonyl Allylation
A highly enantioselective three-component coupling of 1,3-butadiene with a variety of fluorinated or nonfluorinated alkyl halides and aldehydes has been achieved relying on a Cr/Co bimetallic catalysis system. The strategy established here facilitates straightforward introduction of the privileged fluoro functionalities into homoallylic alcohols from bulk feedstock materials in a highly anti-diastereo and enantioselective manner.
