✦ Synopsis

Enantiopure Derivatives of 1,1,2-Triphenylethane-1,2-diol by Unusual Ring Opening of Its Cyclic Sulfite.

-Reaction of the diastereomeric mixture (II) with the alcohols (III) or the diols (V) leads to the formation of the enantiomerically pure ethers via an SN1-type ring cleavage. Treatment of (II) with NaN3 furnishes the enantiopure oxirane (VII).
