A series of cis-2,6-tetrahydropyran-4-ones was synthesized from the intramolecular cyclization reaction of β-hydroxy allylketones in the presence of Me3SiOTf as catalyst. The β-hydroxy allylketone was prepared from allylation reaction with β-hydroxynitrile without protection of hydroxy functionality under the Barbier-type reaction condition.
