Acetalization of Enol Ethers with Alcohols under Visible Light Irradiation Using BINOLs as Photoacid Catalysts
We gratefully acknowledge the Recruitment Program of Global Experts, the Beijing National Laboratory for Molecular Sciences (BNLMS201913), and Fuzhou University for the financial support.
Abstract
Appropriately substituted 1,1′-bi-2-naphthols (BINOLs) are demonstrated as effective photoacid catalysts for promoting the acetalization of enol ethers with alcohols under irradiation with visible light. The reactions proceed efficiently with a wide range of substrates under mild, near neutral conditions.
