The present invention relates to a process for the organo-catalysed kinetic racemate resolution of compounds of the general formula (II). It is thus possible through the action of catalytic amounts of enantiomerically enriched compounds of the general formula (Ia) or (Ib) to obtain on the one hand enantiomerically enriched optionally N-acylated β-amino acid esters and on the other hand enantiomerically enriched 4,5-dihydrooxazin-6-ones (oxazinones). The corresponding enantiomerically enriched β-amino acids can be formed from both easily separable classes of compounds by simple hydrolysis. [chemical expression included]
