Abstract
Chiral -diacetyl-4,4',6,6'-tetramethoxy-2,2'-biphenyldiol (2) was obta ined by high pressure liquid chromatographic (HPLC) separation of bis( camphanate) ester 4a and successive hydrolysis with hydrochloric acid. The absolute stereochemistry of chiral biphenyldiol [CD(+)301.2]-2 wa s determined to be (aS) by the X-ray crystallographic analysis of bis( camphanate) ester 4b.
