Enzymatic resolution of hindered secondary alcohols: Efficient access to a new simplified chiral auxiliary

2,2-Diphenylcyclopentanol, an efficient chiral auxiliary which bears only one stereogenic center, as well as some related hindered secondary alcohols, were resolved by means of pig liver acetone powder (PLAP) and horse liver acetone powder (HLAP).

New chiral auxiliaries: Their use in the asymmetric hydrogenation of β-acetamidocrotonates

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.
