The methodology of enantioselective decarboxylation was applied to 2-aminomalonic acidderivatives in order to obtain enantio-enriched amino acidderivatives. Full conversion was achieved stirring racemic N-acetylated 2-aminomalonic hemiesters in THF at 70 °C with 10 mol % of a chiral base for 24 h. The catalyst may be recycled. Whereas the commercially available cinchona alkaloids gave poor results
