Asymmetric transfer hydrogenations of β-<ce:italic>N</ce:italic>-substituted enamino esters with ammonia borane
With ammonia borane as hydrogen source, an asymmetric transfer hydrogenation of β-N-substituted enamino esters was successfully realized to give β-amino acid derivatives in 51–90% yields with up to 91% ee by using a combination of Piers’ borane and (S)-tert-butylsulfinamide as a chiral catalyst....

Asymmetric transfer hydrogenations of β-<ce:italic>N</ce:italic>-substituted enamino esters with ammonia borane |
| abstract |
With ammonia borane as hydrogen source, an asymmetric transfer hydrogenation of β-N-substituted enamino esters was successfully realized to give β-amino acid derivatives in 51–90% yields with up to 91% ee by using a combination of Piers’ borane and (S)-tert-butylsulfinamide as a chiral catalyst. |
