Prins Cyclization Using Magnesium Halides: Mild Access to 4-Halogenated Polysubstituted Tetrahydropyrans with a Special Feature

Different 4-halo-substituted polyfunctionalized tetra?hydropyrans were easily synthesized by segment-coupling Prins cyclization utilizing magnesium halides. The moderate Lewis acidity allows transformation of substrates bearing acid-labile functional groups. A solvent dependency of the stereochemistry at the C4 carbon was observed.
