The first successful resolution of rac-a-aminoacetals via diastereoisomeric salt formation with optically pure N-protected aminoacids is reported. The absolute configuration assignment of a-aminoacetal enantiomers is performed by an entirely non-racemizing chemical correlation method involving N-protection and a new efficient hydrolysis step followed by a reduction of the resulting N-protected a-aminoaldehyde intermediates. A racemization method of optically enriched a-aminoacetals is exemplified to allow valorisation of both enantiomers. Springer-Verlag 2011.

The invention relates to a process for preparing α-aminoacetals substantially in racemic form, comprising a step of oxidizing optically enriched α-aminoacetals to the corresponding oximes, in the presence of a catalyst, and a step of reducing the oximes t
