of enone 6 with ethylene glycol gave an adduct from which the α-D-threo (16) and α-D-erythro (17) modifications of structure 2 have been elaborated. It was thereby shown that 2 is not the structure of pillarose. Addition of vinyl magnesium bromide to the ketone 24b gave a slight excess of one allylic alcohol, 25, which upon treatment with osmiumtetroxide and hydrogen peroxide gave directly the α,α′-ketodiol

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.
