Copper( i )-catalyzed asymmetric allylic alkylation of α-sulfanyl acetamides and esters with Morita–Baylis–Hillman carbonates

A copper( i )-catalyzed enantioselective allylic alkylation of α-sulfanyl acetamides and esters with Morita–Baylis–Hillman (MBH) carbonates gave a diverse array of chiral α,α-disubstituted amides in high yields, enantioselectivities and E / Z ratios.
