Zn-Promoted Regioselective and Sequence-Selective One-Pot Joining Reaction of Three Components: Alkyl Iodides, α,β-Unsaturated Esters (or Nitriles), and Acylating Agents
iodides, alpha,beta-unsaturated esters (or nitriles), and acylating agents such as nitriles or acid anhydrides in the presence of Zn metal at room temperature in the same reaction system brought about a regioselective and sequence-selective three-component joining reaction involving first C-alkylation at the beta-position and second C-acylation at the alpha-position of alpha,beta-unsaturated esters (or
