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.
