Article abstract of DOI:10.1021/ja00165a036

Synthesis of chiral β-amido esters 7 with high diasteroisomeric excess was achieved by asymmetric hydrogenation (H₂/PtO₂) of stereogenic β-acetamidocrotonates 6 in which the chirality is present in the alkyl of the ester part. For such a purpose, new efficient chiral auxiliaries such as 2,2-diphenylcyclopentanol (12) and 1,1-diphenyl-3-methyl-2-butanol (13) were developed.
