An enantiodifferentiating conversion of racemic 1,3-alkanediols into enantiomerically pure materials

Abstract Titanium tetrachloride promoted ring-cleavage reaction of a mixture of diastereomeric spiroketals derived from racemic 1,3-alkanediols and l-menthone, followed by benzoylation by Mitsunobu reaction, and the subsequent hydrolysis gave enantiomerically pure 1,3-alkanediols.
