Cobalt-Catalyzed Enantioselective Vinylation of Activated Ketones and Imines
We present here an unprecedented cobalt-catalyzed enantioselective vinylation of alpha-ketoesters, isatins, and imines to deliver a range of synthetically useful allylic alcohols and amines in high enantiopurity. This method employs commercially available and easy to handle catalysts and reagents and exhibits a high degree of practicality. The efficiency, selectivity, and operational simplicity of this catalytic system coupled with the substrate generality render this method a valuable tool in organic synthesis.
