Abstract
| - Asymmetric transfer hydrogenation of N-substituted (3S)-3-amino-1-chloro-4-phenyl-2-butanones in thepresence of Cp*RhCl[(R,R)-Tsdpen] (S/C = 1000) with amixture of formic acid/triethylamine gave N-substituted(2R,3S)-3-amino-1-chloro-2-hydroxy-4-phenylbutanes withup to 93% de in a quantitative yield, and reduction with theenantiomeric catalyst Cp*RhCl[(S,S)-Tsdpen] gave (2S,3S)-diastereomeric alcohol with up to 96% de.
