beta-C(sp(2))-H alkylation of enamides using xanthate chemistry

Access to the gamma-amino-beta,gamma-unsaturated acyl scaffold was established by applying xanthate chemistry to enamides. This original beta-C(sp(2))-H alkylation is regioselective and exhibits broad substrate scope and good functional group tolerance. The large availability of xanthates is advantageous to the scope of the reaction which combines a radical process and a polar reaction.
