The present invention relates to novel processes for the preparation of enantiomerically enriched β -amino acid derivatives such as β -amino esters useful for the synthesis of enantiomerically enriched biologically active molecules such as sitagliptin. The key step involves the resolution of the racemate with mandelic acid.
