Aminolysis and ammonolysis reactions of β-ketoesters catalysed by Candida antarctica lipase are very efficient methods for the preparation of β—ketoamides. When racemic amines are used in these processes, the corresponding optically active β—ketoamides are obtained with moderate-high enantiomeric excesses.
南极假丝酵母脂肪酶催化的β-酮酯的氨解和氨解反应是制备β-酮酰胺的非常有效的方法。当在这些方法中使用外消旋胺时,可获得具有适度高对映体过量的相应旋光性β-酮酰胺。
