A highly efficient synthesis of optically active ferrocenylethylamines via hydride reduction of chiral ferrocenylketimines
Due to using (R)- or (S)-alpha-methylbenzylamine as a chiral auxiliary, and low-temperature regime for reduction of the intermediate ferrocenyl-mono- or 1,1?-bis-ketimines, the corresponding secondary mono- or 1,1?-bis-amines were prepared with high diastereoselectivity. Removal of the alpha-methylbenzyl group afforded the optically active primary mono- and bis-ferrocenylethylamines in high yields. The absolute configuration of (R,R)-3a and (S,S)-3b was determined by X-ray single crystal diffraction. We have developed an efficient and highly stereoselective synthesis of the chiral mono- and bis-ferrocenylamines via sodium borohydride reduction, followed by reductive cleavage of the alpha-methylbenzyl moiety using 5% Pd/C and HCOONH 4. The selectivity was up to 99% de. Copyright
