describes the chemo- and regioselective direct aminocarbonylation of alkynes and aminophenols to form hydroxy-substituted α,β-unsaturated amides in good to excellent yields. The latter are valuable compounds in pharmaceuticals and natural products. By a simple choice of different ligands and additives, branched or linear isomers could be selectively formed in excellent regioselectivity. Using a combination
