Evans, P. Andrew,Cui, Jian,Gharpure, Santosh J.,Hinkle, Robert J.
, p. 11456 - 11457 (2003)
The stereodivergent construction of cyclic ethers remains an important area of synthetic interest, particularly given the ubiquity of C-glycoside derivatives in natural and unnatural pharmacologically important agents. This work describes a series of intr
Multicatalytic synthesis of complex tetrahydrofurans involving bismuth(iii) triflate catalyzed intramolecular hydroalkoxylation of unactivated olefins

supporting information; experimental part, p. 1381 - 1383 (2009/10/02)
A multicatalytic synthesis of complex tetrahydrofurans has been developed involving a Bi(OTf)3-catalyzed nucleophilic addition/ hydroalkoxylation sequence. Complex tetrahydrofuranyl products may be formed rapidly in high yield and with good diastereoselectivity. The demonstrated scope of hydroalkoxylation has also been expanded to include substrates bearing useful functional handles including carboxylate ester, olefin, nitrile, and nitro groups.
Stereoselective Construction of cis-2,6-Disubstituted Tetrahydropyrans via the Reductive Etherification of δ-Trialkylsilyloxy Substituted Ketones: Total Synthesis of (-)-Centrolobine

(Matrix presented). The stereoselective intramolecular reductive etherification of δ-trialkylsilyloxy substituted ketones with catalytic bismuth tribromide and trielhylsilane provides a convenient method for the construction of cis-2,6-disubstituted tetra
