Nickel‐Catalyzed Four‐Component Carbonylation of Ethers and Olefins: Direct Access toγ‐Oxy Esters and Amides

Abstract

Multi-component carbonylation of olefins, a reaction that installs both a carbon-carbon(heteroatom) bond and a carbonyl group across the double bond, is an attractive strategy for alkene functionalization. Herein, we developed a novel nickel-catalyzed four-component carbonylation of olefins with ethers under low CO gas pressure. Using alcohols and amines as the reaction partner, diverse γ-oxy-substituted esters and amides were produced in good yields with excellent functional group tolerance. Notably, Naftidrofuryl, a medicine for the treatment of cerebrovascular disease (CVD), can be synthesized by this process straightforwardly.
