Abstract A highly efficient and enantioselective hydrogenation of unprotected β- ketoenamines catalyzed with ruthenium (II) dichloro {(S)-(−)-2, 2′-bis [di (3, 5-xylyl) phosphino]-1, 1′-binaphthyl}[(2S)-(+)-1, 1-bis (4-methoxyphenyl)-3-methyl-1, 2- butanediamine]{Ru [(S)-xylbinap][(S)-daipen] Cl 2} has been successfully developed. This methodology provides a straightforward access to free γ-secondary amino alcohols, which ...
