α,β-Unsaturated Orthoesters as Michael Acceptors. The Trityl Salt-Catalyzed Michael Reaction of α,β-Unsaturated Orthoesters with Silyl Enol Ethers

Article abstract of DOI:10.1246/cl.1987.1183

In the presence of a catalytic amount of trityl salts, α,β-unsaturated orthoesters react with various silyl enol ethers to afford the corresponding Michael adducts in good yields.
