Asymmetric alcohols were resolved as 1-α-O-alkyl-2,3-unsaturated hexosides. After separation of diastereoisomers, the auxiliary and the enantiomeric alcohol were recovered by transglycosidation. Potential applications include resolution of labile secondary and tertiary alcohols, difficult by existing techniques, and enhancement of ees of chiral alcohols produced enzymatically or by synthetic catalytic methods.

The invention relates to the resolution of racemic mixtures, and in particular to the separation of enantiomers of chiral alcohols utilising recyclable chiral auxiliaries. The present invention also relates to a process for preparing these recyclable chiral auxiliaries using an enantiomerically pure alcohol.
