It was not possible to separate the enantiomers of diacetate 7 or diol 6 by HPLC or GC using the chiral columns specified in the general Experimental Section. Derivatization to the bis-2-chlorobenzoic acid ester or mono- or bis-benzyl ether prior to chromatographic analysis did not improve the separation.
