The gold(I)-catalyzed cyclization of monoallylic diols to form tetrahydropyrans is shown to be highly stereoselective when chiral allylic alcohols are employed. Substrates that differ only in olefin geometry provide enantiomeric products from formal SN2′ reactions in high yields with excellent chirality transfer. The allylic alcohol stereochemistry also efficiently controls the facial selectivity when the substrates include additional stereocenters.
