概要

• 論文の詳細を見る

• Asymmetric catalytic hydrogenations of the entitled compounds were carried out over palladium on charcoal in various solvents to afford <I>N</I>-[(<I>S</I>)-lactoyl]-(<I>S</I>)-proline esters with a d.e.(=diastereoisomeric excess) of up to 59%. The stereochemistry of the catalytic hydrogenation was explained by the "chelation mechanism." And the effects of temperature and bulkiness of the ester groups on the asymmetric induction were also described.
