  • Synthesis and Transformation of New Optically Active Ferrocenes Having a Chiral Binaphtyl Group

抄録

The optically active ferrocene having a chiral binaphtyl group, i.e., (S)-(2’-ferrocenoyl-[1,1’]- binaphthalene-2-yl)ferrocenylmethanone 4, was readily prepared by the Friedel-Crafts reaction of (S)-1,1’-binaphtyl dicarboxylic acid dichloride 3 with ferrocene in the presence of AlCl3. The reduction of 4 with LiAlH4 gave the corresponding (R,R)-diol 5 with high stereoselectivity together with a formation of a small amount of (S, S)-ether 6, while, the reduction with DIBAH gave the (R, S)-ether 6 predominantly. The attempt for transformation of 5 to the corresponding diamine via the diacetate 7 resulted in the production of the aminoacetate 8.
