Optical resolution of C2-symmetric racemic 1,4-diols, 1,2-bis(1-hydroxyalkyl)benzene, was examined using (S)-5-allyl-2-oxabicyclo[3.3.0]octene ((S)-ALBO-V) as chiral resolving agent. Diastereomeric acetals obtained from the 1,4-diols with (S)-A

Several o-dibenzylic diols were prepared reacting organometallics with o-phthalaldehyde at room temperature in ether. The identity of the meso and C2-symmetrical (D,L) isomers as well as their ratio were determined by chiral gas chromatography. The meso and C2 (racemic) stereoisomeric diols were easily separated by flash chromatography on silica gel. A set of 18 α,β-unsaturated acetals were then prepared reacting those, as well as commercially available 1,2, 1,3 and 1,4 diols, with the corresponding methylacetals in acidic medium. A trans-acetalisation procedure adapted to the cases of fragile allylic alcohols or unfavorable 1,6 diols-derived dioxonanes based on a Dean-Stark trapping of methanol was also employed.
