title: Efficient preparation of c(2)-symmetrical chiral ferrocenyl diols by catalytic enantioselective reduction of diacylferrocenes.
abstract: [reaction: see text] Enantioselective borohydride reduction, catalyzed by the optically active beta-ketoiminato cobalt(II) complex, was successfully applied to the 1,1'-dialkanoyl- and 1,1'-dibenzoylferrocenes to afford the corresponding C(2)-symmetrical chiral ferrocenyl diols with high diastereoselectivity and excellent enantioselectivity.
