A versatile route to syn- and anti-α-amino β-hydroxy esters from β-keto esters by dynamic kinetic resolution with Ru-SYNPHOS catalyst

Mordant, Celine,Duenkelmann, Pascal,Ratovelomanana-Vidal, Virginie,Genet, Jean-Pierre

, p. 3017 - 3026 (2007/10/03)

A general and practical synthesis of both syn- and anti-α-amino β-hydroxy esters with high levels of selectivity by the use of Ru-SYNPHOS catalysts is reported. The key transformations include asymmetric hydrogenations of α-N-substituted β-keto esters pro
