Direct Synthesis of Highly Substituted Furans from Acyloins and Active Methylene Compounds Catalyzed by Bismuth Triflate
Bi(OTt)(3) was found to be an effective catalyst for a tandem condensation/cyclization of acyloins and beta-diketones or beta-keto esters to afford highly substituted furans in good yields.
