The enantioselective hydrocarbamoylation of alkenes enabled by copper hydride and palladium cooperative catalysis was developed. Utilizing readily available carbamoyl chlorides, this method can be applied to various types of olefins, including alkenyl arenes, terminal alkenes, and 1,1-disubstituted alkenes, providing α- and β-chiral amides in good yields with excellent levels of enantioselectivity
The highly enantioselective synthesis of chiral amides was achieved by an asymmetric Wolff rearrangement. A bifunctional phosphoric acid catalyst not only expedited the transformation but also controlled the enantioselectivity. The developed method enables the asymmetric addition between potent nucleophilic reagents and ketene species and provides a new approach to chiral amides.
