Stereoselective Syntheses of α-Substituted Cyclic Ethers and syn-1,3-Diols

In the presence of a catalytic amount of triphenylmethylium hexachloroantimonate or a catalyst system of antimony pentachloride, chlorotrimethylsilane and tin(II)iodide, α-substituted cyclic ethers are stereoselectively prepared from lactones by successiv

Stereoselective Addition of t-Butyldimethylsiloxy-1-ethoxyethene to 2-Trichloromethyl-1,3-dioxan-4-ones

In the presence of a catalytic amount of trityl hexachloroantimonate, 2-trichloromethyl-1,3-dioxane-4-ones (1), easily prepared from β-hydroxycarboxylic acids, are stereoselectively attacked by t-butyldimethylsiloxy-1-ethoxyethene to afford 1,3-dioxan-4-a
