The in situ complexes of dimolybdenum tetraacetate [Mo 2 (OAc) 4 ] with vicinal diols give CD spectra suitable for determination of their absolute configuration. Positive (negative) torsional angle in the O-C-C-O moiety leads to a positive (negative) Cotton effect at around 300 nm. The extension of

Each of the chiral 1,2-and 1,3-diols examined was derivatized exclusively to a single diastereomeric acetal by the use of a new axially chiral reagent, 2%-methoxy-1,1%-binaphthalene-8-carbaldehyde (MBC). The absolute configuration of the original 1,2-and 1,3-diols was determined by the NOE correlati
