Stereoselective construction of cis-2,6-disubstituted tetrahydropyrans via an intramolecular bismuth-mediated oxa-conjugate addition reaction
The intramolecular oxa-conjugate addition of tethered triethylsilyloxy substituted α,β-unsaturated ketones mediated by bismuth(III) nitrate pentahydrate provides a mild and efficient method for the stereoselective construction of cis-2,6-disubstituted tetrahydropyrans. The intramolecular oxa-conjuga...
