Enantiospecific synthesis of 4-(4'-methoxyphenyl)-hexan-3-one as precursor for optically active (pS) or (pR) isomer of (Z) or (E)-3-(2'-((N,N-dimethylamino)methylferrocenyl)-4-(4''-methoxyphenyl)-hex-3-ene

We describe herein an original method for the preparation of enantiomerically pure (Z)- or (E)-3-(2'-((N,N-dimethylamino)methylferrocenyl)-4-(4''-methoxyphenyl)-hex-3-ene possessing a p(S) or p(R) plane of chirality. The key step of the synthesis lies in obtaining enantiomerically pure (R) or (S) 4-(4'-methoxyphenyl)-hexan-3-one whose reaction with the lithiated N,N-dimethylaminomethylferrocene leads to two enantiomerically pure amino-alcohol diastereomers (pS,3S,4R) and (pR,3S,4R), or (pS,3R,4S) and (pR,3R,4S) respectively. Subsequent dehydration yields a mixture of three olefins, namely, two trisubstituted olefins and either the (Z)- or (E)-tetrasubstituted olefin with respect to the starting amino-alcohol diastereomer. Additionally we obtained the enantiomerically pure (R)- and (S)-4-phenyl-hexan-3-one and the corresponding diastereomeric amino-alcohols.
