Allylic hydroperoxides are a class of compounds of versatile synthetic
utility. Optically active diastereomeric hydroperoxy homoallylic alco
hols and their corresponding diols are easily available through horser
adish peroxidase (HRP)-catalyzed kinetic resolution of racemic hydrope
roxides. Here we describe the assignment of the absolute configuration
of the optically active products and substrates obtained after HRP-ca
talysis by the circular dichroism exciton chirality method. Moreover,
the analytical-scale separation of the enantiomers based on multidimen
sional gas chromatography on chiral columns is presented. Since the en
antiomeric elution order on the ciral columns was constituted, the abs
olute stereochemistry of optically active allylic diols can easily be
deduced by their retention times on beta-cyclodextrins. (C) 1997 Wiley
