REGIOSELECTIVE CONVERSION OF O-PROTECTED GLYCIDOLS TO FLUOROHYDRINS CATALYZED BY TETRABUTYLAMMONIUM DIHYDROGENTRIFLUORIDE UNDER SOLID-LIQUID PTC CONDITIONS

A number of O-protected glycidols are regioselectively converted into the corresponding fluorohydrins FCH2CH(OH)CH2OX by reaction with catalytic amounts of Bu4N+H2F3- and a molar excess of KHF2. Most of the protective groups (X) examined are stable under the above conditions, moreover stereogenic carbons are not affected.
